I have built the main frame of my ox and I have started testing the motors but I have an issue which hopefully some one can point out what I have missed! I’m using a gshild v5 to control the ox but it won’t connect at the 115200 baud rate only at 9600. I have the latest firmware on the arduino uno and running universal gcode sender 0.9, I have checked this using the arduino software and I can monitor the serial port at 9600, 14400 and 28800 baud rates, but at 115200 it shows gibberish! Has anyone else had a issue connecting at the 115200 baud rate and know how to fix this?
I had the same issue. I had the arduino nightly and will be reflashing it tomorrow to the stable build. 9600 was the old standard for grbl
Nuts I uploaded the wrong file Twice, at least it was a easy fix thankS!
Hmm I run grbl 0.9c (or,d, or e, whatever is 3 weeks old) and it works fine at 115k – he changed to 115k a while back now…
I have the same setup as you Ryan too, gshield + arduidiot.
Hi Michel I have the motor working now I was doing to many things and uploaded the same wrong firmware twice. Looking forward to getting it fully running but have a bit to go still, motor and inverter are on its way just need a mount Goethe motor and do the wiring. As you have a similar set up how have you wired it? Have you attached the shield to the back of the X Aries or do you have it elsewhere?
Hi Ryan. I mounted the spindle using a 3d printed mount (see my G+ feed for the link). I have all the electronics mounted at the back of the X gantry, all mounted on a removable plex plate. It’s OK, could be better. I’ll take a couple of pics tonight to show you.
The spindle I kept entirely separate, as it has it’s own control box and so on – I haven’t configured grbl to turn on/off the spindle etc as I haven’t found it necessary so far.
Have you bolted the 2 X rails together? it’s probably a ‘mandatory’ mod on the Ox…
Hi Michel, some images would be fantastic, I will also look for that mount as I have not been able to find a meal one locally at all, looks like I need to get to printer working again sooner it was on the to do list!
Well I have found a metal one from aliexpress, but it’s really ginormous, and doesn’t fit anyway. The one I designed can also be configured to be cut out of 4mm+ aluminium plate, but I havent got aroudn to it yet (the plastic ones work!).
It also has an option to mount a LAZOR (!!!111!) off center to help aligning the tool.
I will give your design ago, I know soone who might be able to cut the part for me, if not I’ll get the printer on the job. A laser module is part of the plan once it’s up and running.
