I am setting up a T8 engraver and using carbide create to create the g code, so fa so good.
I can load the g code into the grill sender(v 3.6.x I think), so far so good.
When it sends it to the machine (T8) it follows the path but does not lower the cutting bit.
Any help would be appreciated
I looked through the tutorials again and nothing I am setting up is different to what they show.
I have built a few 3D printers and basically this T8 is a small machine very reminiscent of the printers.
So to keep file sizes down etc I drew a 30mm dogbone square, that would be cut into the middle of a 100mm square of mdf 1.5mm deep, and set up the job along with outputting the g code. I set the machine going and from the start the machine took a z path to the start point, which I thought a little strange. It then did a complete circuit without touching the board and then did two more passes cutting into the mdf.
I then looked at the g code and I noticed there were no spaces between the instructions, I know they are not needed, and that the first z up was after the co-ordinates but before the move command. I put the z up first then the co-ordinates followed by the move command and the path to the start point was now in a straight line. I still had erratic z movements though. I felt the z motor and it was definitely warmer than the x and y motors, not hot just warmer. I let it run the same design over the same bit of wood and watched the z drive during the run. The z motor was positive during its lift and drop stages but periodically it would make random moves.
It is possible that either the z motor or the driver board is faulty, this is all new from gearbest. Tomorrow I will change the driver board and if that does not work I will change the motor.
The results will wing their way to you.
I hope you and yours stay well during this pandemic and thanks for your attentions
Swapped out and the motor runs cooler, that’s a plus, but still have z axis issues. Will swap the motor out tomorrow.
Changing the sequence of the gcode definitely improves the route to the start position. Will see if I can send examples.
