At high speed the gantry was binding especially when it was cold in the garage. I found that lubing it helped but just yesterday it started binding even at warm temperatures. I had recently reverted to original settings when I re-installed LaserCut.
It seemed that the left side was the one hanging up and I noticed the belt on the right was considerably tighter.
Help: What is the method to properly tension the belts?
I loosened the belt and the problem seemed worse so I went back to tight.
I then loosened the left belt on the side that was sticking and completely removed it from the drive shaft in the back of the machine. I figured that it would bind even worse but surprisingly it did NOT bind at ALL!
So, I am stumped.
I put the belt back on in what seems to be only one position that it naturally goes to but I'm not sure that is correct. I cut a 5.2mmx5.2mm square and got a 4.8 by 5.0 rectangle out of it. It's not bad but I thought I'd calibrated to within .02 but that was just a light cut mark on plastic.
Help: Does belt tension affect parallel cutting? or anything?
The binding was the same so I changed my quickspeed setting in LaserCut and the binding stopped as I had done before. Note: In LaserCut I had a difficult time finding the setting that changed the test speed. Turns out that besides changing the Settings and then Download CFG to set the machine (goes BEEP) you ALSO have to Download Current to get the settings to take effect. Seems odd but true.
Anyway, any help on the belt and Gantry problem?
