The plasma cutter was in terrible shape, it had 3/16" wobble and grind as it moved along the X gantry.
The grind/wobble was because one of the gantry bearings broke which in turn tilted the gantry which caused the pinion on the X axis to rub against the Gantry which in turned damaged the pinion.
Me and Ian Jaeger took it upon ourselves to maintain the machine, I managed to replace the bearing assembly and we tuned up the pinion. Everything is running a lot smoother now.
I was actually quite surprised that people even wanted to use the machine while it was in that state, I know it isn’t a world class machine, but with a little maintenance and love it can cut some really nice parts. I hope in the future that people raise an issue when our machines are squealing/grinding/wobbling so that we can work together to get them fixed.
