Ok, I realigned the slide bearings to the back wall and now it's cutting nearly perfect.
Thanks so much for your help Thom!

Re: Shark HD4 extended isn't cutting square...
Thom, I just checked the alignment of the bearing blocks to the back of the frame, it looks like that is indeed the problem. I can't get calipers in there to measure but there is around .1" gap on the left while the right is up against the back wall. That would explain it exactly. I just talked with...

Re: Shark HD4 extended isn't cutting square...
Gotcha. I figured that was the best test because that’s the size dowels that I’ve seen people use for two-sided parts. I re-ran that same test(still with 1/4” holes) but turned my rpms all the way up while slowing the plunge speed down to 10ipm. Same results. I guess in MY head it wouldn’t matter wh...

Re: Shark HD4 extended isn't cutting square...
Also, the mdf slats have been milled “flat” using a pocket hole program and a 3/4” end mill, 02” pass depth so I don’t use virtual Z.
I’ve had the machine for about two weeks.

Re: Shark HD4 extended isn't cutting square...
Am I being too critical? The fact is I can’t machine two sided parts and I can’t cut a rectangle with 90deg corners. If I wanted to cut the parts for a simple jewelry box I couldn’t because they wouldn’t be square. Nothing would fit. Is 1/16” out of square in a 12” span acceptable? In my experience ...

Re: Shark HD4 extended isn't cutting square...
Thanks for the reply Thom. The set screws that were loose are not the 6 that hold the gantry to the crossbar. It's the set screws that are on the slide rail car. Here's a pic of them: IMG_2235.jpg It's the black set screws in the aluminum piece. I have since tightened them and ran another test. No l...

Shark HD4 extended isn't cutting square...
When I cut a rectangle profile it does not come out square. I believe that the gantry is not square to the Y axis. This problem also showed itself when I drilled four symmetrical reference holes for a two sided part; when i went to flip the part the holes did not line up correctly. I ran a 3,4,5 squ...
