and then 'do the math' (-: HOWTO Calibrate your CNC Machine for MACH3 or GRBL
Hi There are a few plugins for unwrapping 3D objects into flat panels, you will have to google it. Also, this video might help... [MEDIA]
Wiring the G540 to an Arduino running GRBL is a perfectly good way to go. This guy used a CNCshield as an interface to the G540 Running the...
You might also look at real milling machines like the PCNC440 from Tormach. Tormach Personal CNC (PCNC) | Small CNC Machines You can upgrade it to...
Reading GitHub - robottini/grbl-servo: grbl 0.9i with Servo motor support it looks like they are trying for a very wide range of motion by giving...
Those 2 lines are very short arcs with very large radii and so long as the controller is in relative IJ mode they should not pose a problem. Put...
make sure there is nothing connected to the Uno that might prevent it resettting when the IDE tries to program it. or, press the reset button...
time for a new motor? test that motor on both drivers, if it does not run at all, then get a new motor. if it runs on one of the drivers, time for...
If you run one motor at a time (on the same driver), what happens? Does the gantry move the same distance on both motors? I ask because I just had...
Even industrial ball screws have to be calibrated. Most industrial controllers allow for a table of correction factors to be entered to cater for...
check the current setting on the drivers, they must both be the same. check the microstepping settings on both drivers, they must be the same....
You did reboot the Arduino after you changed $6, right?
The 8x8 leadscrew supplied with the C-beam is quite capable of sub 0.01mm resolution. 8mm pitch 200 step per rev motor 8 microsteps 200 stepps/mm...
A minor update: Help updates added MAC help section arcmoveij() is INCREMENTAL mode. the 'incremental' form of IJ is used so make sure you set...
so only during rapids with 2 axes in motion? (do both stop or just one?) then either you have electical interference between the wires, or your...
Turn your microstepping down to 1/16 (and don't forget to reset steps/mm in Mach to half the current value). This increases the available power....
It will work fine Bruce, but you are wrong when you say the pocket tool will not work. As of version 1.4c, it will work. The top cut is 9/64"...
Material thickness is applied when the Gcode is generated. That is why all other depths are percentages! This way you can cut 'half way...
SketchUcam v1.4c has been released. Features in this release Help updates added 3D help section arcmoveij() now always used for arc outputs Old...
There is no way to set the width on a line cut, it always uses the current bit. There are 2 ways to cut your slot: 1 - add a parallel line each...
