TechoCNC LC series issues

[Python]

I am having some problems with this machine.

My configuration is:
Techno LC4896
Porter Cable motor
Enroute

My main issue right now is speed/quality.

When doing a hatch fill on shapes smaller than let's say 1 1/2"
the edges distort at speeds above 25 ipm.

It was suggested that perhaps the bearings in the spindle could be the culprit, but I have used several of the same motor before and never seen this.

Techno has not responded.

Can anyone help troubleshoot this?

TIA,
Wes

Call Techno, I'm sure they will help. They have good documents for checking machine alignment etc. I have a 054 gantry machine which shares a lot of parts with the LC but I have a spindle not a PC router. You don't mention bit size, depth of cut, material etc. Do simple test cuts like the box test come out OK ?

[Python]

Many different bits produce the same results. Here is the output sample I sent to Techno. I think the motor could be out of square.

Techno did not respond because we had the wrong email address
We are usually successful in getting their tech support on the phone and getting good help. So, not Techno's fault..

I'm running a LC4896 with PC. If you want to send me the Gcode I will run it on my machine and photo the results.

Normally, I remove the material with a volume or pocket cut operation and then profile the outer walls of the pocket.

I have 2 Techno LC machines. a 4896 and a 59120.
I am crazy about both of them, and have yet to have an issue.
For your problem, Maybe you could run a simple grid of 12" squares and circles and see how they look over the length of the table.
Just a thought.
