Hello,

Is anyone already switch original motherboard to 32 bits motherboard with Marlin 2.0 firmware on ATOM 2.5EX ?

I would like to replace my original board by SKR V1.3 motherboard or SKR Pro v1.1.

This is a project for the moment, but I think other people have same idea...

Thanks for you answer

徵求賢人:幫我在 ATOM 180529 版本的 Marlin 選單當中,加入 Delete file in SD 的選項。

理論上不難,指令是 M30 filename,只是我不會改 Marlin……

賢者請私訊,,願致薄酬。

把Atom 2.5 單噴換上32位元版與LV8729 128微步。

換完後真的幾乎無聲,只有在回抽時稍明顯一點,但還是比風扇聲音小。但還有一些問題需要調整。

終於可能讓 Atom 2.5 連夜趕工不擾人了!!!

在自己改熱床後就拿掉尿帶把供電全都交給明緯電供,所以就順便把LCD固定件旁的開關改成LED燈的控制開關/最後一個影片,方便晚上查看列印狀況。

使用的是

開源板 Bigtree skrV1.3

驅動IC LV8729

韌體 Marlin2.X

當時的想法是如果只換版子(開源)跟Drive IC其他可以沿用的話,就能維持Atom的外觀(但LCD2004似乎配合上會有問題)!

# 列印件速度是50mm /s 層高0.2mm

# 工事進行中

# 待整個完成度高一點再來分享

# 只有單噴版本

Printer has gone crazy!

This short video shows what happens when I run AutoLevel. The same things happens at the same place when I run AutoCalibrate.

I've reloaded the Ver. 2018039 firmware with no problem. And yes, I did the Load Failsfe/Store Memory after uploading.

Could I have a bad stepper motor or stepper motor driver chip? There is nothing physically wrong with the printer, at least as far as I can see.

Yinka Alade

It looks like it thinks the printing bed is larger than it actually is

Birk Binnard
2019-10-02 02:33:36

I've been printing on that exact same bed configuration for over a year. All of a sudden the printer seem to lose track of where Z equals 0 is. I have no idea what the problem actually is.

Yinka Alade
2019-10-02 03:27:39

Yea, no idea. I'd replace the motherboard and see what happens.

Birk Binnard
2019-10-02 04:01:07

I've had the same thought. Do you have any suggestion on which MB would be a good replacement? (Good = will run with vanilla Ta At om2 firmware.)

Cherub Shiao
2019-10-02 06:39:25

WOW really crazy @_@

If the touch sensor can work well, u may change the printing area by using smaller diameter, like 210 or 200 to c if it can work or not.

or u just change the spring on the screw of touch sensor? maybe the spring too hard for touch sensor?

Yinka Alade
2019-10-02 06:43:07

I remember at one point I was using a different board that wasn't from the Atom dudes and my prints were always just not perfect. It could have been me and my settings, but they were off. I also had to reverse some numbers in the settings to get the other board to work. At some point I bought another new Atom board and started using that. Let me look up the non-atom board

Yinka Alade
2019-10-02 06:45:22

MKS BaseV1.2 3D Printer Controller Board (RAMPS 1.4 + Arduino 2560 remix board)

this was the name of the board. I bought it on Amazon from Keyes themselves but the item is no longer on Atom being sold by them.

Yinka Alade
2019-10-02 06:45:59

and that was recommended by the Atom dudes as a replacement for not using their board

Birk Binnard
2019-10-02 07:36:40

Hmm mm. Not exactly encouraging. I'll do some research and see what I can find.

看到真懷念剛裝好atom那時的情景

Birk Binnard
2019-10-02 10:04:14

Cherub Shiao The sensor is the standard Atom2 micro-switch. It works fine ; the auto level function runs perfectly up to the place shown in the video.

Birk Binnard
2019-10-02 12:44:33

Amazon has that board for $37.77 which is fine. But it has a different shape which means the mounting holes will be different, so attaching it to the Atom2 frame will not be simple.

Also it looks like the stepper drivers are soldered to the board and not plugged into connectors on the board. This means there's no way to replace a driver if one goes bad. I've saved an old/bad Atom2 board just to have some backup stepper drivers if needed.

Remove the spring during bed leveling

Birk Binnard
2019-10-03 10:28:41

Dan Salvador That's an interesting suggestion that would never have occurred to me. I don't see why it would change anything, but I'll give it a try and post results here. Thanks.

Birk Binnard
2019-10-03 13:15:30

I was really surprised, but removing the spring allowed AutoLevel to complete OK.

But now I have a different problem - the printer fails to remember the Z-Offset setting. Each time I set it and then do Adjust Offset the printer behaves like the offfset has not been set. I may be able to compensate for this by setting a Z-Offset value in my slicer.

Dan Salvador
2019-10-03 14:22:08

Birk Binnard well known issue , during the first print after the bed leveling adjust the offset

Birk Binnard
2019-10-03 22:52:06

Well it certainly wasn't well known by me! But thanks for the info.

I haven't been able to make a first print since completing the bed leveling because the printer crashes the hotend into the bed as soon as it starts to print. And I have re-adjusted the offset after this happened and it didn't fix the problem.

I'll go through the whole process again and see what happens.

Birk Binnard
2019-10-04 07:05:02

Since the AutoLevel completed OK (after removing the spring from the Z-Min adjuster screw) I thought I'd try Auto Calibration to see if that helped things at all. But that function crashed the hotend into the print bed on the 4th move. So there is still something wacked with the printer.

I wish I knew what it was.

Birk Binnard
2019-10-05 10:58:54

After a considerable time testing and checking I found 2 problems, one of which I was able to correct:
1. The small metal flap on the Z-Min micro switch was disconnected from the switch and stuck, by magnetic attraction, to the inside of the end effect or frame. The flap is small enough to hide inside the curve of the frame, so it was difficult to spot. But I finally did find it and after partially disassembling the hotend was able to reinstall it on the bottom of the microswitch.
After this I was able to successfully complete an Auto-Level and Z-Offset adjustment - sort of (see #2.)
2. I'm beginning to suspect some sort of internal EEPROM error because the Z-Offset value keeps getting messed up. Here's a typical scenario:
Perform Adjust Offset and set proper offset using the LCD knob
Perform Adjust Offset again to verify it is OK. It isn't.
Check Z-Offset value on LCD. It is far different from what it should be
Change Z-Offset vaue to 0.00
Perform Adjust Offset again and re-adjust to proper value
Check Z-Offset on LCD - this time it matches previous setting
Run test print with Layer Height = 0.200 mm
First layer prints ok, second layer shows 0.300 for part of the layer, then switches to 0.400, third layer shows 0.400 then switches to 0.500
Stop print and check Z-Offset; it shows 1.32 which is far off from previously set value.

All this leads me to believe I do need a new motherboard.

Yinka Alade
2019-10-06 05:42:29

Birk Binnard I had an issue before where my z offset like yours would just do wild stuff. That was the first time I replaced my board. Second time I replaced it was when I had that shirt I showed you way back in messenger.

Birk Binnard
2019-10-06 06:44:06

Well I'm going to try a different slicer just to ensure it really is a printer problem. I don't much like the idea of replacing the motherboard, but I've done it before so at least I know what to expect.

Birk Binnard
2019-10-06 09:05:56

Well there is definitely something wrong with the way the printer handles Z values. I used a different slicer (Craftware) and had similar issues with the printer's Z height when printing.

My layer height is set to 0.200 mm, but after printing the fir st layer, layer 2 showed 0.100 mm for a while, and I could hear the nozzle tip dragging over the traces from layer 1. Before layer 2 was finished the LCD switched it's display to 0.200, but that didn't seem to make any difference with how the printer was printing.

Layer 3, which should have been at height 0.400, showed as 0.300 and had the same dragging effect as layer 2. I stopped the print soon after noticing this.

So similar results from 2 different slices printing the same part makes it pretty clear there is some sort of problem with the printer itself. I thought about a bug in a stepper motor or stepper motor driver, but if that were the case the hotend X-Y position would be off from what it should be, and it's not. Only the Z value seems to be wrong.

This suggests there is either something wrong with the firmware itself, or with the way the motherboard's firmware is processing the input GCode. So it looks like I need to find a new motherboard.

M503 dump setting again.
M500 for save setting

Birk Binnard
2019-10-07 11:18:54

Thanks Clarence - I will try that. But I doubt I'll be able to make sense of the EEPROM data.

Birk Binnard
2019-10-07 12:32:30

OK - I tried that series of commands. They seemed to work OK. But printer still doesn't handle Z-Offset properly. When I do Adjust Offset the printer needs an adjustment of 1.350 mm to position the hotend at the proper height. After I do this the Z-Off set reading says 3.175. Then, if I go back and do Adjust Offset and re-adjust to 1.350 the Z-Offset value says 6.10.

Of course I know that Z-Offset is limited to +/- 2.00, so there is something very strange (at least to me) going on here.

I've got the text of those M commands if you want to take the time to look at it. Can't post them here (of course - FB is such a pain) but let me know if you want to see the output. Meanwhile I've been looking at possible replacement motherboards.

Clarence Lee
2019-10-07 12:55:38

How about check the belt, wheel etc. Might need to consider something loose in mechanical.

Birk Binnard
2019-10-07 13:13:28

Been there/Done that. All is OK.

Even if that were the case it wouldn't explain the Z-Offset values being so strange.

Clarence Lee
2019-10-07 13:27:36

It's the farest edge, consider the cable might cause sensor not work as expect at the specific place. Try to loosen some signal cable length

Birk Binnard
2019-10-07 14:50:42

OK - thanks. I'll check all the stepper motor cable connections. That is something I had not thought about.

Nope - all the cable connections are OK - I checked both ends of each. I also made sure the stepper chips were all firmly set in their sockets - they were.

I created a mod log for the work I am doing on my Atom 2.5 EX. Once I get more core functionality done, I will be uploading the Duet 2 WiFi firmware to GitHub. I will branch off the parts that wouldn't work on the stock 2.5 EX. Feel free to weight in and give me input.

The first description has some goals of what I have on my road map.

Amazing, thanks for sharing! How did you do the enclosure? The acrylic seems embossed, but maybe it's flat.


原文網址 John Wachowski
2019-05-30 11:00:34

I think I made progress, but still could use some help identifying what is going on here. It looks like massive over extrusion, but I'm not positive. Maybe bump down my acceleration on the extrusion steppers or something?

UPDATE: It appears the g-code from Atom support was sliced with something incompatible with the RepRap firmware that comes with the Duet board. I sliced my own stuff using "5D absolute" for extrusion and everything is good to go now. If anyone else has this problem it's likely because you're using incompatible g-code.

Birk Binnard
2019-05-31 02:13:26

Looks like massive over extrusion to me too. Easiest way to verify this is to set the slicer's Extrusion Multiplier to a number lower than 1.0. Try 0.5 to start with since it looks like you've got twice as much filament being extruded.

Note that the b oard's firmware has parameters defining the diameter of the extrude gear (and other things) that actually determine how much filament gets extruded by the GCode the firmware processes. So it could be that your extruder gear is larger than the firmware thinks it is.

John Wachowski
2019-05-31 02:18:34

This was most likely what it was. I updated the post and now have a working printer once again.

Birk Binnard
2019-05-31 02:23:19

Congrats for getting it sorted. Have you tried doing an AutoLevel? A "quirk" of the Atom firmware is that it inverts the Z-Min microswitch setting which is not the case with standard Marlin firmware and I suspect not with other flavors also.

John Wachowski
2019-05-31 02:27:16

Birk Binnard with RepRap you can invert the switch to trigger when it goes on or goes off. I will be creating a guide later for upgrading your Atom 2.5 EX to using a Duet 2 board. I'll also be sharing the configs I wrote.
