Re: Raspberry Pi Wifi Remote-controlled gcode sender

Will / Bob, I bought the Raspberry Pi camera, with this thought in mind. The problem is it has a short ribbon cable that attaches to the raspberry pi. So if I want to go that route, I need to keep the R-Pi with camera right next to, and travelling with the tool. This means a long USB cable to the Ar...

Raspberry Pi Wifi Remote-controlled gcode sender

I decided to liberate my laptop from my basement, where my loud, dusty Shapeoko resides. So I set out to build a solution that would combine my Arduino/gbrl with a WiFi-enabled, RDP-enabled Raspberry Pi to create a single solution allowing me to remote into my Shapeoko from anywhere in my house with...

Re: grbl stops at some CamBam-generated gcode

DanMc, your suggestion was successful. I replaced those trillion-line polylines with circles. The gcode size dropped to 1/10th. Best of all, everything was cut properly (for the most part - but that's another post). Now I know what to do with future CamBam-interpreted DXFs. Thanks to all! Paul. P.S....

Re: grbl stops at some CamBam-generated gcode

Okay, I replaced my cheap USB cable that was touching many areas of the power cable and transformer with a fancy, overpriced, well-shielded USB cable, carefully routed to avoid proximity to power sources. The results were the same: it tries to spit out around 2000 lines of gcode to make a 3mm hole b...

Re: grbl stops at some CamBam-generated gcode

it's about as likely to die at any point in the G-code, but if arcs are 90% of it, it's very likely to die during an arc. cvoinescu, That is undoubtedly true. This gcode file has over 10,000 lines, many thousand unnecessarily dedicated to a couple of small holes consisting of a multitude of tiny li...

Re: grbl stops at some CamBam-generated gcode

Thanks IC, as always. Just what I think I have a handle on predictability of a process -- whether it be CNC milling or 3D printing -- another variable injects itself into the process to collapse my hubris. Another weekend, another family-excusable chance to spend time figuring this stuff out! Paul.

Re: grbl stops at some CamBam-generated gcode

Okay. I was barking up the wrong tree. There was nothing in the gcode that was causing the problem. The problem was that my computer would disconnect from the Arduino/grbl at varying points. This only would happen during the slow time where the CamBam-interpretation of the DXF file would render a ci...

grbl stops at some CamBam-generated gcode

I have been trying to make an enclosure for my Shapeoko electronics and I have run into a snag. I created the box shape using inkscape with the T-slot Boxmaker extension. This is what it looked like in Inkscape: 11-11-2013 12-08-54 PM.png I then saved it as a DXF (the only format common to Inkscape ...

Re: Using VNC on Raspberry Pi to send gcode to grbl

Thank you very much, Bob. I had no idea that I could RDP into my Raspberry Pi (I RDP into everything else). This will save me time!

Paul.

Re: New Shapeoko build acting very strangely

One thing that has saved me much time that you should try if continuity testing shows no wiring problems: Use a multitester to measure the resistance on your Nema 17 coils. It should read around 6.4 Ohms +/- .2. Obviously you need to measure it on an individual motor, not the Y motors in parallel. I...
