Talked to +Chuck Schwarz at open hack day yesterday. He's been poking at the Solidoodle and says that we have two issues that keep us from having better prints with it.
1) the extruder gets overflow and underflow due to voltage irregularities. Some time with a multimeter tweaking the motherboard will fix that.
2) he thought that we were getting banding because the Z-axis screw was oblong, causing jitter on the X and Y axes, but testing with a laser points to the issue being uneven travel in the Z axis, with the fix being replacing it with a screw with a finer pitch. Looks to be less than $20 but has a not-easily-reversible step.
If I got anything wrong, of course he can correct me; LTL has been very enthusiastic in correcting my errors.
I said that, to whatever extent he needs permission to go forward with 1., he has it, but for 2., there should be group discussion. I see that as happening a week from Monday. Comments?
