UPS arrived this afternoon so I got to work building 'Luke" our m4. All went well , firmware updated to 0.66.3 and I was able to retract all belts after increasing /Maslow_Retract_Current_Threshold to 1800.
Now im trying to extend the belts and it’s not going so well. I cant pull on the belts without extreme force. I was able to do this to loosen a few mm but it wont extend any further.
If I push the belt in , it unwinds a little which I can then pull out another few mm of belt but this doesnt feel right and also seems to be causing the belts to overlap/get tangled.
It seems that editing the config using the web interface may be buggy. I was getting error 152 , until I manually uploaded the Maslow.yaml again.
After hard powering off , both the left belts were able to extend. Neither on the right would extend.
After powering off again, the bottom right belt (and the two left belts) were able to extend normally.
The right top belt is not able to extend still unless I push it in , and then it lets me take out the distance I’ve pushed it in.
I thought I just have reversed the encoder ir something,., but this is exactly the same behaviour all arms were exhibiting before I fixed the config file issue and they’re working fine now…
Updated to latest firmware this morning and it’s doing it again. Retract all was fine , but extend isnt letting any of the belts loose. If I push the belts inwards I can retract that same distance.
Tried the dirty 1000mm firmware with fresh Maslow.yaml just for the sake of trying something different and still cant get any of the belts to extend unless I push them in a bit first , then it’ll let me take out that amount (plus whatever was already out)
This is all after last night running a successful 4x6 calibration, so I don’t think it’s hardware related… but I wouldn’t put it past me to have stuffed something up
