slipping material

[the_skeptic]

Hi

My material is slipping when when cutting. It did not slip when I carved. I am using pine for a practice cut which could be part of the problem. I also see this with other hard woods such as when I do an edge route.
The rollers were cleaned
the encoder tracking wheel seems to be ok
Y axis travel is 15.528"(-.078" to 15.468")
the y belt was recently tightened (per the carvewright tech support suggestion, who sent me a video)... I have to run more tests..
I recently upgraded the firmware with the latest file which got resolved the insure sliding plate is set message.

Does this problem look like a y axis issue from the photo and is the message in the 3rd photo giving any clues?

Thank you for any insight and help.

What is your head pressure?

[fwharris]

It looks to be off in the X axis and to me the full carving is off in the X axis direction.

Was this a single pass or multiple pass cutout?

[the_skeptic]

Multiple. max cut depth .1" per pass.
Thank you

I agree. Did the tech think that the Y was not coordinating with the x and missed?

[the_skeptic]

I did not measure, but the roller sensors show that they are enguaged

Every pass you make increases chances of it mistracking. Make in as few as possible and ONE PASS is preferable. Low head pressure could cause it to mistrack.

What are your sled tails length. Sure looks like 3.5 inches.... I always do 4 inches... 3.5 inches lets the board "Tighter" on that roller "EDGE"... I like the extra 1/2 inch...

I would try the same project again with a set of 4 inch ears... When the board it at the 3.5 inch point it can "RELEASE" enough pressure on the board to let it loosen up on the BRASS ROLLER leading to the result you see....

And Edge Routing is not the machines strong point...

And you have masking tape on the bottom of the board so the brass roller has something bit into?

I do use tape on the base, but am not sure if it was on that run. Good suggestion for the extra 1/2" on the sides. The problem did happen at the edge of the piece. I'm also going to check the outter support roller. The problem did not occur with the carving, but there seems to be more lateral force applied when cutting.

Thanks,
John
