I'm sending it to the included nano controller, just connecting the two via USB. The pausing doesn't matter so much, but it seems like it's missing steps and getting off track.
I have a script that sent GCode line by line quite nicely from my laptop, but it shudders and hesitates (ultimately missing steps and getting off track) when I send from a Raspberry Pi. Is there a better way than sending commands line by line? Can I upload a whole GCode file at once to the port?
Amazon might have the same belts: https://www.amazon.com/Meters-Rubber-Aluminum-Printer-Rostock/dp/B075YN647Y/ref=pd_day0_328_5?_encoding=UTF8&pd_rd_i=B075YN647Y&pd_rd_r=ZNPKAZE34DDT4AKXGQ5B&pd_rd_w=O2Hcg&pd_rd_wg=PUpht&psc=1&refRID=ZNPKAZE34DDT4AKXGQ5B
Think (hope!) that I found the rails here: https://www.tnutz.com/product/exm-2040-20mm-x-40mm-smooth-t-slotted-aluminum-extrusion-new/
That's mega cheap!
Can anyone confirm that these are the correct parts?
There's some info here: A5 physical dimension extension kit
Does anybody have a current supplier and, especially, specs for the rails? 40mmx20mm for the big rails, 20mmx20mm for the small ones? What's the T-slot width?
Anybody experience cable management issues with runs that long? I'm assuming that I'll just splice cables into the middle of the existing ones.
I found the belts on Banggood, but does anybody have another distributor that won't take so long to ship from abroad?
Well, it seems to work fine with Chrome GCode Sender app with Windows, so it's a port/device ID issue with OS X, I think. I'll report back when I figure it out. Think that there's a driver issue with Nanos and Sierra that I'll investigate.
I did remove the laser power cable, just to make sure that I didn't get any unexpected laserings, but didn't think that'd be an issue.
When I plug in the USB cable, I do hear what sounds like fans powering up on the controller.
I'm trying to control my A3 manually. I have a python script that'll do it, I think, but I'm getting no response from the A3 to G21, and certainly nothing from G1.
To rule out the python script as the issue, I tried the Chrome GCode sender extension. It'll connect (port: /dev/tty.lpss-serial1), but no joy there, either. I also tried with another sender, and same thing: connection, so response to commands. Any ideas?
I'm trying to use the A3 as the base for a CNC zen garden (I'll attach a magnet to the top of the carriage and use it to pull a steel ball through sand from below). It seems like it'd be possible to control the XY hardware using an Arduino and stepper controller - is that true? Is there any easier way to do it, like sending commands to the A3 controller board from my external Arduino?
