I got the whole thing set up and then went to try to move the z axis all the way down. I noticed that only one side was going down. I checked the connections several times and they look all right. I tried to plug the motor that wasn’t working into the other side of the board and it started to work but the other side then stopped working. I was able to only retract 3 motors and am entirely unable to extend any of them.

Hi @bar, I have a similar issue with my 4.1. I have actually seen both working but only twice from maybe hundreds of attempts. Once it worked, it completed a couple of jobs but when it was power cycled I had no luck. I tried repeating the process to get it working again but it isn’t repeatable.
Hi @bar I also have this issue. I built my kit yesterday 4/19. It was super fun by the way and relaly enjoyed it! Its amazing the kit all uses the same hardware fro everything. So cool and the quality of the plastic is really great. Ok back to the issue:
Only one side of the z drivers works. Here is what I did to troubleshoot without sucess:
Reinstalled the firmware (Newest version)
-Tried switching the motor cables, the either z axis motor will work but from only one of the connectors. The bad side is the one closest to the USBC port. The good side is the one near the XT power connector.
-Checked the board for bad soldering near the connecotr pins, did not see anything,
Checked the pins to make sure they were ok, did not see any issues.
restarted mutiple times,
I could alwaywas get one side of the z axis to go up and down but the other wont turn the motor.
I have a video of the issue I can send.
So I got the new board and set it up and drove the z axis all the way to the bottom. Both motors worked going down but it looks like one of them didn’t go down all the way and was 1/8" or so away from hitting the bottom and now it won’t go up or down and since there’s only an 1/8" gap I can’t change it with my hands. Any ideas here?
I had a similar problem, I assembled my Maslow 4.1 at my dining table, connected to my laptop via my home wifi, installed the latest firmware, V1.03, and tested the connection by controlling the z axis and everything seemed fine. Finished building my frame and began the calibration process and immediately discovered that now one of the z axis step motors was not working.
Switched the cables around and then the other z axis step motor would’nt work which meant the motors were fine it was the board. For me it was the port opposite the power input that wasn’t working.
Tried updating the firmware to 1.04 and got an error message “Error 1 : upload rejected, not enough space”
But much to my surprise both z axis motors were now working. Very odd.
To update firmware do I need to delete the existing firmware files?
Regards
Steve

to upgrade to the 1.x firmware you need to use the USB port. normally you can
upgrade via the web page, but the 1.x jump made it able to use twice as much
space and isn’t able to be done via the web page

That is odd, @bar, something you want to check into??
I had a similar issue. I assembled the 4.1 unit with firmware 1.03. I lowered the z- axis all the way per the steps. After that, one of the motors wouldn’t lift. I ended up taking it apart and by the time I put it together, the 1.04 firmware had been released. I installed it and after that, both z-axis motors worked. I assumed it was an assembly issue, but it’s possible it could have been firmware
I just tried updating the firmware and seeing the same behavior:

Switching the cables didn’t help, same one stays stuck (although at some point I did get it do all the way down and eliminate that tiny gap)
This to me sounds like maybe an alignment thing with the stepper motors. If they are a little bit further apart or a little bit closer together than the threaded nuts on the router side they can bind up when the z-axis gets all the way to the bottom.
Can you try loosening (but not removing) the four bolts on the bottom of the sled that hold the stepper motors in place, then lower the sled all the away down, and then tightening them back up? That will make sure that where the motors are mounted is in line with the threaded nuts.
Hi there, I recently commented on a youtube video about one side of my z axis not going up and down. You told me to comment here to receive a code for a replacement
