I was about to give up on here. Think I resolved issues. Switches, table direction, homing..... Now I need to figure out why the 1 inch circle example came out 3/4 and oval. Did the 100mm thing,measured out. Although x axis seemed to stall and slip on section of it.couldn't find any binding.
Actually Dave I pushed thru what I had questions on.at least I hope so. Made repairs again, homing switches work again, direction is correct on each axis,settings are in.if I can figure out ANY of the cad softwares ,I'll try my own circle test. Very frustrated. I don't want to be a CNC specialist. I just want to make a few simple signs, maybe drill precise holes to replace bad parts on machine. Arduino, I've made a bunch of useless stuff. multiple node wireless motion detection, garden control (temp,water,humidity), etc.
4d, you suck!
So, my fix for the x end switch didn't work. Added a block to hit switch, caught by the thickness of a paper. Thankfully I use rubber hose so it just pulled the rod off the drive. OK, some questions....
Garage sale I got artcam something. Does 3d stuff, really confusing and more than I am ready for.and a few freebie programs copied to CD.I just got updated versions. Gcode sender 3.6.1,gcode 1,i have Corel print house 4 ,inkspace, gimp, hoping I can draw what I want, make it gcode and cut.
We just bought Carveco which is the new company for ArtCAM. To learn the program I'm going through the ArtCAM tutorials on YouTube. Any of the Express or Standard tutorials will work to get you familiar with the program.
Got it running. It goes home without ripping anything up!!!
So I got a few dxf files from scan2cad site. How do I resize them? I tried mm instead of inches, (program says dfx doesn't define), it still shows 200 inches.
The g-code for a 200mm cut is the same as the g-code for a 200 inch cut.
Your CNC Controller reads units. If it's configured in mm's, it will cut 200mm's. If it's configured in inches, it will cut 200 inches.
If you want to scale it to some other size, you can do that in any CAD program that reads .dxf files.
Sounds like Jeff is trying to do this below going on the cheap. Download Vectric's trial versions (don't know if Careveco has them) and play around with them. Also watch their tutorials. You'll throw those older programs out in a heartbeat. You'll save yourself a LOT of frustration and anguish. Then worry about the machine. I don't know anything about yours so I can't say anything good or bad about it. But remember -- this will not be a cheap venture. You can cut some corners, but don't think you're going to get away with a freebie. I thought all you had to do was scan, size, and hit go. Ain't so!!!
John, I just downloaded aspire. Yikes! $2000. Nope!!! This is a hobby not a lifestyle. Anyhow, I did a 1 inch circle and square gcode sender and aspire set to inches. MAYBE 1/8 inch drawing.been playing with anything I can get to test. Sketch up,gimp, you name it.does anybody know which format to save in? Different .nc files gave error codes in gcode sender. One actually turned Circe into a square!!!
Jeff how about downloading VCP/Pro instead of jumping to Aspire since you want to do simple stuff.
There's a bunch on here that are doing that sort of thing for no monetary reasons, maybe just to learn a new tool
and have fun. Freebie = headaches and grief as Jerry pointed out already if not familiar. at least you can upgrade
to Aspire if you really dig VCP and want to do 3D
What I need to do is stick with one and learn. artcam seems good but not sure about just 2d ( just make a simple engraved board ("the Smiths").
Aspire seems good but $2k is steep and don't understand the size issue.
I need a 1,2,3 step lesson. Reading,videos are slowly getting me there but I need simply how to do simple to get started.
