Did you buy everything from here?
Everything but the conduit and 3d printed parts were purchased from the shop on 3/17
Are you using end stops?
Mac or PC (windows xp, 7, 8, 10?)?
I am halfway through carving a large (6’x4’) topographical map of the Great Lakes out of rigid foam insulation for an ecology class at my school. (I’m the librarian.)
The map is divided into 2’x2’ sections to fit inside my machine, and I’ve been able to cut three sections nicely:
However, the last few attempts have severe z-height issues:
There is a gradual slope bedward with each new cut, highlighted when the machine skips and later returns to a section.
After digging in these forums over the past few days, I am almost certain this has something to do with the max Z speed. Because Estlcam cannot turn a high-res raster into gcode, I am using Vectric’s Aspire 8.505 to render it. I used John’s post-processor here for a while, then when this issue cropped up I switched to Klaus’s here yesterday. That increased the xy travel speed, but did not solve the problem completely.
Am I right in thinking the error must be bad gcode? The issue pops up in a similar way regardless of where the cut is made on the machine:
The gcode for this particular section is too large to upload (~8MB), but I am happy to clip it down if someone tells me what to look for.
…and my Repetier settings, if that helps.
Thanks for your time!
