Im not 100% this is the spot to put this, but here goes…
I am a new owner of an xcarve 1000, and completely new to the CNC scene. being an IT guy, i built a simple computer to connect to it and installed things like fusion 360, inkscape, UGS (2.0), and the easel drivers.
in Fusion, i have downloaded and installed the post files for xcarve and easel. I have created a project to engrave a surfboard and letters into a guitar.
I created the gcode and uploaded it to UGS. It looks right, but the tip of the surfboard is 2 inches too far to the right, and the z axis never went down (should be a 1/16 deep cut). i ended up lifting the scratch board that im trying this out on, to see what was being cut.
in UGS the x and y values should be 0 i think, they are -29 (-750mm). even after I hit reset zero, it still shows -29 underneath the bigger number for x and y.
I calibrated the machine using a caliper and the wizard
I have attached as many pics as I can to help illustrate what I have done. where are my errors stemming from?
Do you have home switches? Did you home it? Does it then show negative numbers after homing? This can be an issue, as it is with mine. I end up just closing the UGS and reopening it without re homing it a second time. This is because traditionally, cnc machines had home to the far right, not the near left like the X carve.
1 - How do you set your work zero in UGS?
My workflow is as follows:
Power machine ON, command $H to do a homing cycle (this syncronise machine coordinates with design coordinates)
Jog to my intended work zero position (Click Reset Zero)
Send gcode to the machine and carve
2 - The negative or positive figures are arbitraty and can be ignored. As long as the machine have performed a homing cycle any set work zero´s or parking spots (G28/G30) are stored as offsets relative to the homing switches and are persistent (Untill changed)
So you can power OFF, power back ON and run $H and same work zero is maintained.
Where is your drawing zero in relation to the x carve? In many cases, I make the home switch location the zero on my drawing and that makes everything simpler. In the event of a power failure or lost steps ( like when I run into a clamp for example), I can just rehome and start again. This is just my way of dealing with some of the X controller quirks. Also I have just kept the stable older version of UGS and it is simpler and works. It sounds like you just need to make the Fusion 360 settings a bit different than what it is now. I don’t use F360, so I can’t speak to that.
my workflow currently with UGS (this is my first cut using it) is to connect, home the machine, and manually move z axis to the work piece. I realize that i didnt disconnect and reconnect UGS after all that and that could have caused my issue. ive played with a few different steps, but still working it out
I have little experience in the CNC scene, and I dont find UGS that cool vs Easel (for some reason, sometimes my machine stop working properly until a cold reset if I use UGS… work coordinates get all screwed or something like that).
If you create an sketch in Fusion 360, project the geometry, and then save that sketch as dxf, it will import perfecly into easel and you do no have to deal with UGS.
I kinda like Easel myself but tend to use UGS (v1.0.9) when I export from Fusion, simply because the UI and reliability of UGS suit me better. Easel have all these pesky “Confirm this…that” steps that need to be done each carve
I have not tested the DXF export - Easel import of DXF yet but from what I gather is that its working good.
Something in OP’s workflow is messing up his result, I’d like to know why
