Hi there!
After an initial cut a few months ago, life got in the way and I’ve only now come back to the Maslow.
Around the time of the initial cut, the retraction threshold was getting quite high, so I decided to do some maintenance and see if I could make things a bit better. Unfortunately I made them worse!
Here’s what I did:
- Disassembled arms, applied some grease as the bottom two were binding up
- Reassembled, ran calibration
- machine would always stop at the bottom right and get stuck in endless calculation (left overnight multiple times)
- Found I put too much grease and it was being affected by the cold weather
- disassembled again, cleaned out the grease, applied silicone lubricant
- re-assembled - with the arms from bottom to top: BL, BR, TR, TL
- same issue with the calibration - gets stuck in bottom right
- re-flashed firmware 1.7, uploaded fresh index and Maslow.yaml
- Ran calibration on 500x500 3x3 - successful
- moved machine around the spoil board - when getting to the bottom left, the bottom two belts started to get loose
- Maslow seemed too tight in parts, bottom of sled was lifting, jerky movement
- applied silicone lube to bottom of sled - same issue
- tried re-calibrating on a 5x5 (?) and 1000x1000 grid - again stuck on bottom right.
