SOLVED! TL;DR needed more weight on the sled. More info below original post.
I’ve just finally set up my first Maslow and I want to love this thing so much….but I have not been able to get a decent cut out of it.
My main issue is that vertical cuts on the far left side of the board pull to the right by about an inch…meaning my straight lines 90º very quickly become squiggly near- 45º inclines. I’ve attached a couple photos of what I’m getting.
(Green = What the cut should look like / Red = what I’m getting)
My horizontal lines are perfect and vertical lines in other areas of the cut look good…it just seems to happen within 4-6 inches from the edge of the board.
I am using a triangular, ring kit from Maker Made with a z-axis. Here is what my setup looks like:
(with spindle and vacuum)
Things I’ve tried:
Recalibrating automatically (Literally 10s of times)
Recalibrating Manually (Probably about 30 times)
Ensuring the correct measurements between motors, the top of the work surface to the motors.
Resetting the correct chain length (More times than I can count)
Manually adjusting the chain sag correction (Though truthfully I have no idea what I’m doing here)
Manually adjusting the Chain tolerance
Adjusted spindle speed (best at about 12,000 RPM)
Just in case it is helpful, here are my measurements and settings:
- Motor to motor length - 117.5 in (2,984.5 mm)
- Top of surface to motor height - 18 in (457.2 mm)
- Rotational Radius used - 5.44 in (138.176 mm)
- Bottom Chain feed
I hope all of this information is helpful! I really want to get my Maslow up and running and have been beating my head against the wall for the last few weeks over this issue. ANY suggestions you may have would be greatly appreciated!
Thank you all so much for all of the great ideas and comments. It ended up looking like @Gero and @dlang were right on the money. While I did not end up lengthening the top beam, I did upgrade from those bricks to some weights I found at Walmart (inspired by a bunch of threads here). I increased the weights from 5lb on each side to 7lb and that instantly solved the majority of the issue.
It is still pulling to the left about 3 mm…but I think that has more to do with what @dlang suggested about better centering the ring on the sled.
Thank you all again for the quick and helpful comments! I’m excited to FINALLY start cutting!
