This started with groundcontrol on an old laptop pre-covid, but we never quite got calibrated.
But covid’s endemic now so we started to get back into it. Getting caught up in the reading [here], there were a lot of new updates, so we decided to restart from the start with the new knowledge that has accumulated over the last 3ish years. We had been using an old laptop and groundcontrol, but when we read the updates we switched to a raspberry pi and webcontrol fresh without importing the groundcontrol.ini file.
Alas, we now cannot seem to get to the “triangular calibration” test.
When we run the “Test Motors/Encoders”, left and right work properly, and Z tries to work but will no longer move the router up and down. It does move the Z connector to the router, but it can’t overcome the static friction and just wiggles in it’s slot back and forth.
Then I do the “Set sprockets and chains”, and everything again seems to work well. I did do the whole thing from scratch to create the marks on the chain, but now I just reset the chain to those marks on the motors and hit “set zero”. All of which seems to work very well.
But, when I try and manually drive Z for a longer run to see if it can move the router if given more of a chance, or in fact when I try to interact with the device in any way other than previously mentioned, all that happens is that the right motor whines, the sled drops, and then the entire system freezes up.
We have tried:
-Wiping eeprom settings
-reflashing fresh 1.26 firmware
-reburning raspberry pi SD
-trying new SD card
-redownloading the program from both github and eastbaysource
Including all but new SD card at once now for 3 times in a row, the only difference being changing from github to eastbaysource.
One thing we did notice, the eastbaysource installation was noticeably faster in the “test motors and encoders” and the other things we tried, MUCH smoother even though the software claims to be the exact same file.
But other than that, when we try and do any high level interaction with the machine, including triangular calibration, all that happens is the right motor whines and drops the sled a bit, and then everything wedges and “stop” flashes, with no error messages shown.
We’re at a serious loss here. We really want this to work but have no idea what we’re possibly doing wrong. I’ve got the dimensions memorized I’ve put them into the quick calibration so much.
Help me Obi Wan Kenobi.
You’re our only hope!
