Cool project. I would move the rails for the Glass holder down lower and then use multiple braces for the dispenser rack. To be honest, I would...
And if you don't want to mess with soft limits, switches aren't that expensive and easy to add. A lot of machine kits ship with no limit switches...
Good point. A Nano cost like $3.
I suspect you need to run shielded wiring to your switches. If you do, make sure the ground/shield connection is at the controller. Honestly, I'd...
First, you need to get Arduino working for your atmega32. Is there a port for that? There appears to be for an ATMEGA 32U4. Then you will need...
I think you should take a look at recent micros. CAN bus is getting cheap. The Teensy 4 has CAN bus support with library support - $20 for a 600...
Big thanks! Yeah, probably needs a test. A 5V tolerant micro might be needed.
Yes, Terje, the guy behind grblHAL, is using LinuxCNC as his model. Already he has a number of G and M codes that go beyond - like M62-65, pin...
one other questions, the ad shows a card that mentions 5V. I assume that since it's just switches, 3.3V would be ok too. Is that right?
After looking at it a bit more, it looks pretty usable. On the pulse generator, I assume that A and B are quadrature encoded. Not sure why bar A...
Thanks. I like that. May well get it. However, I still want to support the USB versions as I am working with others to help make grblHAL a...
Do you a link to one (or 5)?
Not for my needs. I want to be able to plug pendants into a grblHAL breakout board like the one I made here.
You can do that but really what you need is functioning Arduino board support. Then it's a simple matter of telling GRBL which pins are which...
Thanks. That means I'll need USB OTG capable micro. Probably a teensy 4.
I see a lot of these for sale and would like to experiment with one. Does anyone have info on how they interface to a PC? Does it show up as an...
Probably overkill for your use but in the GRBL/GNEA wiki, there is discussion about sending commands to GRBL from application. There might be some...
huh? Not sure what you are disagreeing with but GRBL/GNEA most certainly runs on the mega. You have to configure it before building. Plus, the...
it exists now. You need to download the grbl/gnea code and configure for the mega and RAMPS. To be honest, RAMPs is a poor choice for a breakout...
OK, looking at the machine I see that so you really can't use a standard homing sequence at all. I thought your problem was that you had loaded...
