I am new to the CNC world and have been frustrated for the past month trying to figure out why my designs in inkscape-> JSCUT-> ChiliPeppr are not milling to my designs. I am trying to cut 1/2 inch cast acrylic sheets with a depthpass of 1mm. I designed a 100 mm diameter circle and it cut a 114mm circle. I used the correct tool diameter and settings in JScut. I believe it might be the way I initially configured my settings for the tiny G. Ive just changed a bunch of setting and i think ive screwed it up even more. I can find lots of shapeoko settings but nothing much for my openbuilds OX cnc machine. The X and Y axis moves really jerky when i try to jog it around. Where can i find the correct settings i should be using with my electronics and hardware?
Dual Gantry with nema23
-x,y,z using nema 23
-GT3 Timing Belt X,Y axis (60mm per revolution,I think)
-Tiny g powered by 24v 14.6 a
-Tr8*8 acme screw
Odd movement at the end of each travel. Seems the steps/mm on X and Y were 80, and Z was 400. I don’t recall what jerk and accelerations were off the top of my head.
I just drew a 98 mm circle on inkscape. loaded the svg file to jscut. put in correct tool diameter .250 inch and told to cut outside. When the gcode loads into chilipeppr its path is 110.8mm diameter. the disc cuts out at 104 .5 mm. The gcode in chilipeppr corresponds correctly to what is cut but not to what i designed. I am probably making a rookie mistake. Please help!
It sounds like your problem is Inkspace to Jscut then. I found that the px per inch setting is really critical in Jscut to let it convert your SVG units to real world measured units. I screwed up a job last weekend due to my px per inch conversion being off. Maybe @Todd_Fleming has some ideas for you.
