Cant update to Holey Firmware, and cant get the software to run outside of Docker

WebControl Troubleshooting
1

So I was just given a V1 Maslow, built my standard sized frame, got it all up and running…

And I cant seem to get my firmware updated to holey. I can flash the standard firmware and hook it all up, and it moves around, I can set the chains all that…

But when I flash the most recent holey firmware from here it doesnt connect/move.

When I try to flash the prebuilt image of webcontrol, its not compatible with a pi 5 so I cant boot, I followed the steps from the github here and it throws a 203 exec error when I try to start webcontrol using “sudo systemctl start webcontrol.service”… So I finally did it via the docker, but the docker appears to be on 0.94 which according to This thread I need to use a firmware from eastbaysource which doesnt seem to be hosted online currently…

Ive also read that I need to use a prerelease 0.95 version to update the firmware?

Im a little confused can anyone point me in the right direction?

Edit: Found this thread so im gonna try to flash with 32 bit --edit2: ended up trying .957 first instead

Edit2: Releases · Orob-Maslow/WebControl · GitHub Found the prerelease versions gonna flash back to 64 bit and then try .957

Edit3: For time travelers I installed raspbian 64 bit latest fresh install

Then

cd ~
mkdir webcontrol
cd webcontrol
wget https://github.com/Orob-Maslow/WebControl/releases/download/0.95-beta/webcontrol-0.95-pre-release-beta-rpi-singlefolder.tar.gz
tar -zxvf webcontrol-0.95-pre-release-beta-rpi-singlefolder.tar.gz

This downloads the 0.95 beta, then follow the steps from the github GitHub - Orob-Maslow/WebControl: Web-based Ground Control

Before you go to start the program, you must, go into

/home/pi/webcontrol and move the contents of the webcontrol folder inside there and move them back out.

So the contents of /home/pi/webcontrol/webcontrol get moved into /home/pi/webcontrol

Make sure to take a copy of your webcontrol file, and that its permissions are 0755

This doesnt get you avrdude, but it does get you closer…

Final edit: After spending a day, just install 32 bit and then follow GitHub - WebControlCNC/WebControl: Web-based Ground Control

You can flash the firmware directly from webcontrol, no need to do it manually. Webcontrol .94. I don’t use raspi so I can’t help there.

It looks like .95b is the newest version to work, which it seems to work fine.

Except the maslow is now throwing errors of not keeping up every time I try to move. I know this thing works because I got one holey calibration out of it. Honestly though im starting to get frustrated to the point that want to I salvage what parts I can (router, chain) and throw the rest in the trash.

Power supply is putting out 12v, input voltage is regulated with a line interactive UPS. Tried another power supply, the power supply is connected to the control board…

When I tell it to move 5mm down, it moves .5 inch up and says it cant keep up.
Test the motors? All 3 test fine.
set the sprockets? Can spin each motor forever 1 at a time, no issues.

Try to just move the z axis some? Moves up half an inch without moving Z, and says it cant keep up.

Changed Position Error Limit to 20 from 2…

the can’t keep up error is common, you need to either slow down the feed rate
you are trying to cut at, or go into the settings and change the limit that
triggers this.

Unfortunantly, this machine never got acceleration planning implemented in any
firmware, so it assumes that it goes from a dead stop to full speed instantly,
and throws an error if the planned position differs from the actual position by
more than 2mm (by default)

most people change this value in the settings to 20 or something huge to disable
it.

if it’s moving up when you tell it to move down, then you probably have the
chain over/chain under value set incorrectly for how you have the chain
positioned. a picture of your setup and settins would help (is the slack on the
outside or inside of the sprocket?

ok, that should have addressed the ‘can’t keep up’ error, but the fact that you
are moving in the wrong direction is a big problem.

How do I slow down the jog buttons on the website? Because thats what ive been using to test motion (outside of the motor test)

I ended up changing it to 2000 and that still didnt fully help, but good to know that mostly disables it

I would agree with this, but I can assure that you that I have that part setup right because when it does move it moves in the right direction. The issue appears to be something like “when youre supposed to move, just go up” Angles, down, right… all does it, just jumps up.

the chains go over the top of the sprockets to the sled, and is setup as top in the advanced settings, and I set the chains by 12ing the sprocket zeroing and then telling webcontrol to move the motors 1651 mm using the set sprockets menu, and then connecting the slack to the sled.

I found another thread… somewhere that said that someone soldered their z axis connector, and I was just out there and wiggled that connector and it started to work, I think it might be the z axis connector failing, at least thats the only thing thats made sense so far.

I think the most frustrating part so far is that I ran through a full holey calibration 2x. So I know it moves and works, but it hasnt worked/moved fully in 3 days other than the one time after i wiggled the Z connector.

I think im gonna see if I have the stuff to remake/terminate the Z connector and if I dont im gonna solder it

Update: Tried soldering it, and remaking crimps… Didnt work

so I just bought a new motor and cable. I think im getting close but who knows.
