Share Your GCode / Engraving on a cylinder

« on: September 29, 2020, 11:07:58 PM »

i have a 5 axis router/engraver and I'm looking for g-code that will allow me to engrave something on a cylinder. or if i have to adjust font size and mill a flat on the cylinder and engrave on that? thanks.

P.S. I'm well experienced with mill and lathe BUT I'm a complete newbie to cnc anything.  Again thanks

General Mach Discussion / 3040t 5 axis 800w USB Chinese cnc router/engraver bing3040TFIVE TS001-BFIVE

Motor tuning help.

I purchased a Chinese cnc router. its a 3040TFIVE usb 800W.  i finally got the bootleg copy of mach3 from the supplier that had many of the settings in it that got everything kind of working (don't worry i have a licensed copy of both mach3 and mach4, so I'm legal). I'm having a devil of a time getting the motors tuned.  I've tried every setting i can find online so far and they work ok but the z axis is dodgey.  i can confuse the steppers in manual by hitting the directional keys fast and the z axis will bounce up and down. i can press page up and it goes up press page up again and it goes down or hits the top and goes down (i have no limits installed yet) same with page down.  when i go into automatic the z axis does not move. here are my settings.


X,Y,Z,A,B
steps = 2000
velocity = 1999.8
acceleration = 300

Kernel speed = 25000kH

if i'm not mistaken the bob will go up to 100KHZ


Motor output

X,Y,Z,A,B,C,SPINDAL are all checked everything else is 0 or X then step and dir port ate all 1 except axis C they are 0 like all the other settings.

Please let me know what else you might need.

Thanks.
