I’m learning the ropes from a software perspective so this may be a dumb question…
I’m doing some helical drilling and the tool path is not what the preview suggests or what I was expecting. I made this video to better show what I’m dealing with:
As you can see, both ESTLcam and Repetier suggest the too will follow a spiral path from the middle of the hole. But the tool ends up following an odd pattern which results in a not-so-perfect hole…
On a side note, I’ve tried several times and on some tests the router travels way too fast during the cut… odd, it seems random when using the same settings over and over.
The other thing I noticed is that when I start a job, the tool starts about 1mm higher than I had set the starting point. Not sure if this is a safety measure built into the system which is added to the depth of the cut, or if my cut is actually 1mm short as a result… It’s visible in the above video when the tool starts routing the hole above the foam.
…obviously a minor issue compared to the above but may or may not be related to incorrect settings somewhere.
I just purchased the kit from your site a couple weeks ago (I’m the one with the faulty STOP switch that was an easy fix). So it’s the RAMBO board with I believe the only LCD option you had available on your site. I chose the dual endstop option. I did not change firmware or anything else on the RAMBO board…
I’m using Repetier Host to initiate the job. I was wondering how to use something else just to rule out a possible issue with Repetier… can I just upload the GCODE to an SD card and print from that perhaps?
The issue is your gcode. you have not done a zero offset because of your dual endstops. It all makes sense now. You are centered on zero, meaning it will not move negative, you will only ever get a pie shape that way.
Yes, not using dual endstop firmware. You can also turn off the softstops, if you update the firmware I have just added it as a LCD option in the menu.
I’m actually going to do a little more cutting as is before upgrading. Now that the ARC issue is resolved, I want to make sure everything else is running well before making any changes.
