Left motor comes on with Ground control off when i update to firmware 1.26

Hi I’m have issues in the UK. when i update the firmware to 1.26. with ground control off the left motor just just start. when I open ground control, i stops for a second then starts. ive check ground control is showing correctly connected and on the right version.

Power looks good with both USB and power light showing on. usb shows connected. when i also do a test motors. they all fail

I’m a bit stuck as i only received my kit a couple of week ago and cant proceed any further.

Please help

I think I just replied to you in a different thread, but lets keep the conversation going here instead.

My first instinct is that it could be the wrong firmware for your board. Who did you get the kit from?

If they have their own firmware the pins might not match which would result in something like you are describing.

Eastbay source. Com the board is a tb6643 v1.5b

I did think that but have not managed to find anything that says I should use different firmware

Fantastic!

I have the same issue however my shield is makermade from makermade.com.
Left motor spins continuously
Right Motor was spinning continuous but stopped after 1.26
Z works perfect

I am new to this and have had the kit in the garage since January. Built the frame, friday, followed the assembly guide on Saturday and spend yesterday troubleshooting the motors all day.

Some things I have tried

If I plug Left or Right motor in to the z axis on the board - they work as expected

Tried different cables and have swapped the left and right motor around in just about every possible combo. MP1 always spins CW, MP3 does not spin or activate the motor and MP2 always works.

Thanks in advance for any help.

Are you positive that it isn’t the issue with where the firmware came from? Where did you get the firmware that you are using?

Hi
Thanks for the response, I followed the MaslowCNC.com/assemblyguide. The site I pulled the firmware from was http://github.com/MaslowCNC/Firmware/releases/.

After I connected the motors I notice both the left and right motor was running, and stayed running after the firmware was applied. I continued on, and did another firmware upgrade through webcontrol to see if I could get the motors to stop. I tried Upgrade Stock Firmware:1.26, rebooted everything and it did not help. I tried the Upgrade Holey Firmware:51.27, did a full reboot the right motor stopped to function at all and the left continues to run. Tried the custom also 101.25.

Read through the forums, and did the move cable to port test, after going back to Firmware 1.26. moved each motor on the same cable through each MP. All motors function correctly on the MP2.

I now cant get any movement out of MP3.
Any other ideas?

Thanks

Did you reset your EEPROM after flashing? open the arduino IDE serial monitor, connect to the arduino and type $RST=*

You might try getting your firmware from here:

Version 1.28 should be the latest and will cover the newer shields, though the 1.26 should be good enough to run all but maybe not the latest Eastbay and prototype boards.

Mine was defo firmware related as eastbay source was 1,26b

All sorted now. Firmware issue. Eastbay source running 1.26b. I went via maslow site an used 1.26 hence the issues

Thanks for the response, I did the reset eeprom from webcontrol. I will try from the IDE and try the 1.28. Stay tuned and again thanks everyone.

Thanks fo the reset tip.
I did the reset and then flashed from the link you provided (thanks for that also)
In fact WebControl verified the firmware correctly.

The results:

MP1 Motor running continuously and then jitters on direction 1 but resumes on direction 2 never stopping

Who did you get the kit from?

MakerMade thru Amazon, I just tried an older firmware and MP3 started running none stop.

I found a ELEGOO mega 2560 in my bag, I am getting the same exact result with it. Where can I source a makermade shield, I dont see them on the website.

1.2 is an older version of the board, but it should work with all of the recent firmware versions. Makermade is a kit supplier for the Maslow open source cnc machine. Makermade.com would be where to get the shield if you wnat the same one. MetalMaslow and Eastbay also sell them. It kind of sounds like your motor driver chip on the shield might be toast, but that would be a guess. How long have you had the shield?

Wow quick response, thanks. I have had it since January, but this is a STEM project with a couple of students so we have taken our time building the project. planning first. Once we figure it out we plan on purchasing a couple more to have the class build. We put the plan together last month and then last week Friday built the frame, early Saturday fired up the Arduino. The second we hooked up the power supply both motors were running and after watching a few videos looking a forums we figured something was wrong. I volunteer my time and $ for this and want it to go well. Not a great way to start but I am willing to do what ever it takes to make it successful. I will check out MetalMaslow and Eastbay. Until then I will order another makermade kit and use the parts. Thanks for the help.

send an email to makermade (look on their site support@makermade.com?) since they made your kit and see if there is something they can do before you just buy another kit. Metalmaslow sells just the shield (for $41 I think it was the last I looked), but the 3 kit suppliers are usually really good about helping you out with hardware failure. If they cannot, then unfortunately I don’t have a spare shield right now or I’d help you. Maybe someone on the site has a spare? ANYONE??

I followed your advice and ordered one from MetalMaslow, plus a spare just in case. I did sent an email to makermade, but have not heard back. With the short school year and the Covid impact, we dont have much time to get this one done and then get two more built. I really appreciate your help. I think I am enjoying this more than the students, I am hooked… Thanks again!
