I will have a look when I dig out the arduino, but I don't think i have a record of the settings that worked well since jumped around a bit...
strange, I had no problem doing a number of test setups with GRBL. default settings ran all the motors I tried, and tuning for speed etc 'just...
steppers like high voltage, so use about 80% of what your drivers can do. most small drivers are rated to 30 volts, so use 24 volts. however,...
another local supplier to gawk at http://www.cncmachines.co.za/index.php?option=com_content&view=article&id=65&Itemid=25 R30k? are they serious?
then the standard C-beam will do it fine at 0.0025mm per step. (8mm lead, 200 step per rev motor at 16 microsteps at 24 volts) I don't...
I used to use a program called EasyTrax that ran under DOS. It did plotting very well and I had forgotten that. I have been trying to use Eagle...
how about this thread? http://openbuilds.com/resources/howto-calibrate-your-ox.145/
hmmm, in Africa I see, welcome to the club! I am in Grahamstown. and don't worry about having stuff shipped here, Mark does a brilliant job of...
I think you need a C-Beam machine, it has the rigidity and the accuracy for doing PCB work. remember that the copper layer is very thin and you...
looks good! This is the one http://sketchucation.com/forums/viewtopic.php?t=13563 use the 'convert to polyline' option after selecting all the...
looks like a nice plan so far Johnny. have a looked at the now discontinued lathe software LazyTurn ?
remove the tool change command 'T1 M6', GRBL does not understand that. you may want to try SketchUp + SketchUcam - very good at generating GRBL...
that is quite clearly broken! outside tool must apply to the outside of a face otherwise the arc processing gets broken. you could work around...
it has nothing to do with the face and everything to do with the way the lines were drawn or edited, how Sketchup stores them, and how it gives...
I have just looked at your file and found the following: your radbones are too small. you have the bit set to 0.125" and when I click the...
a week or two. (-: apart from 4th axis: hole grids countersunk holes counterbored holes multiselect pockets (select many faces and pocket them...
soon to be released next version of SketchUcam will support simple 4th axis stuff...
apart from non-flat drawings causing issues.... there is a problem with complicated outlines, the offset routine that creates the cutline can get...
no idea, but as the thread name implies, I know that SketchUcam will work just fine
motopreserve, you may want to try GRBL-Panel after UGS, I find UGS a bit clumsy and GRBL-Panel much nicer. ymmv of course....
