this resource HOWTO Calibrate your CNC Machine for MACH3 or GRBL will teach you how to do the calibration manually. Using those methods, you can...
Yes, I quite agree, it should be doing a G53 Z *safetymove* before moving to the current WCS X0 Y0. You can create a little gcode file for...
Being short on table space myself I do like this idea for a laser marker/cutter. I think putting a sheet of aluminum foil under the foam will...
just to confuse you, here are some more things to watch and learn from (-: https://www.youtube.com/results?search_query=clough42+laser
note that if you cut about 1/4 of the way through an MDF sheet the resulting surface is like a sponge and will not need holes to transmit vacuum....
please don't ignore this warning [MEDIA]
What you both want to do is look at RCKeith on Youtube who does in depth videos on making and using hotwire cutters. I have helped him with his...
He probably means OpenBuildsCONTROL? it is easy to miss that the GRBL ecosystem is 2 distinct parts, GRBL on the controller itself (firmware),...
Most sources I have seen agree that using full circles is generally bad and will cause some problems on some controllers. I have also seen R...
The probing sequence is a little tricky so please carefully read this page Engraving Curved Surfaces and also watch (on a PC not a phone) the...
no, you do not need to change boards, it won't help. The total solution is to NEVER go to machine coordinate 0. Most of the postprocessors...
are you sure you did all the setup? in particular, after the surface probe you must also do 2 separate Z probes, one to tell the system where the...
Hi GRBL regards a hit on any limit switch as a hard limit and will then stop with an ALARM. This is mainly because the Arduino Uno does not have...
plenty of googleable help on importing a foto into Sketchup, however, That will not get you useful Gcode from SketchUcam, sorry, the 3D module is...
there were installation instructions on the wiki but I see they are missing. I have opened a bug report. meanwhile, follow GitHub - Harvie/bCNC:...
if you watch the video in the link i gave you can see that it is purely a setup operation..... 1 - bcnc probes the object surface and stores the...
I think a better way is probing so you can set the WCS correctly from what you have and then run the Gcode relative to that WCS (or even more than...
You can use bCNC to probe the surface and then use the probed mesh to correct for the curvature. Your Gcode is generated as for a flat surface,...
what bits are you probing with? some coatings on bits are not conductive....
There is no size limit, but there is a TIME limit, little edit box at top right of the 3D display. Code will run fine without being displayed...
