I wouldn't use ACRO for anything that has (more than very small) opposing forces to X or Y moves. I think it would be ok for pushing a pen but not...
And for what it's worth, I have finished the design of an isolated I2C based ADC with a built in divider. Boards are on their way to me from China...
That capacitor will act as a low pass filter to prevent noise. Not exactly best practices but probably better than nothing. Make sure you use one...
On the capacitors, the poster who recommended that didn't understand why you use them. They form part of a Low Pass Filter is causes higher...
Something to consider about the TB6600 drivers you see on the market. Most of them are not really built with the TB6600 chip. The real chip...
Rob, you point out extremely valid issues but Grbl Classic has the same issue - you have to rebuild it. And often you have to make tradeoffs due...
It was a joke based on your use of the worst case wires! Should have put a smiley in. I have a huge pile of crappy speaker wire that I keep...
Yeah the iMXRT1062 is a truly amazing processor, at least until the 1170 comes out... Unshielded lamp wires... Running NO switches I presume!...
Well, there is my Teensy 4.1 based design. It's in my github repository. eagle files and all. Several people have forked it so there may be a...
I think it would fantastic if you guys moved to grblHAL. It really is a quantum leap forward.
I haven't tried it. Probably ok in compatibility mode. You might want to check out ioSender - really well done and unlocks the advanced features...
Insert pitch for grblHAL which pushes the step frequency limit well beyond 8-bit Grbl. My breakout will do 160K.
Nothing slips by you Rob! Yes, Terje is da man. You can see several of his projects in the showcase. Amazing work.
Yeah, that style kill switch is a good idea - I have 4 of them in various uses in my shop. Note though, the Rockler one is not magnetic meaning...
I don't have the machine wired with grbl classic anymore so can't test it but the physical spindle on Z didn't move, it was the sender/grbl...
There are 2 levels of stop - Feed/Hold and EStop. (3 if you count chopping power) You should use F/H to pause your job to, for example, adjust...
Yeah, looks like BB to me too. Unfortunately, even top quality BB can give problems like this. Especially on acute points like in the photo. As...
Perhaps you could post the pics...
A starting point is here. It's more of a simplified overview. Here is the list of additional supported G and M codes over the standard Grbl set....
Glad to hear it. Would hate to hear your project took a hit! You might want to take a look at grblHAL. There is some THC work going there for a...
