connect EN- to ground, and EN+ to 5V now the driver is enabled whenever the power is on.
yes, 2 drivers driven by the same signal is good. both motors then get full power.
confusing. maybe the best is to not use a pin out for this, but instead to just wire them to enabled so the software can never get in the way.
the problem is microstepping and the stepper internals and driver enable/disable. as you can feel, the stepper has preferred step positions, known...
they may be on the other side of the board, or built into the driver chip (-:
sorry, assumed it had just been turned on and zeroed at the current position.
Hi, I am the current SketchUcam maintainer. I don't see the need for this as part of SketchUcam (though admittedly for a lot of holes some sort...
I did mean X and Z to move together, because they are so different in speed capability.
there is something wrong with your max speed settings on the controller. it is happy doing 5000mm/min cutting feed rates, but as soon as it is...
I want to see the Gcode that is generating these motions. If that is wrong the machine will do the wrong thing. You say it jogs correctly, which...
I would orient the rail vertically to minimize deflection due to gravity. put the motor underneath and the camera on top. maybe a plate each side...
when you turn a stepper motor it acts as a generator and make some volts across the wires. since a motor driver is supposed to 'give' volts to...
please send me the sketchup file and your gcode file so I can figure out what is going on.
first, read this http://openbuilds.com/threads/routy-cnc-router-v-slot-belt-pinion.27/page-11#post-2723 26.666 steps per mm is 0.0375 mm per...
I use Sketchup + Sketchucam plugin. I am the current maintainer of SketchUcam but a lot of people have been involved in making it work as well...
interesting, but already superceded by this http://blog.machinekit.io/p/machinekit_16.html
No, I am not saying that at all. the way the hardware works is that it will step the motor to the next position on every low to high, (or...
some big leaps there. good translation of Gcode commands to step or (esp) servo controls is why you pay 6 figures for a real CNC machine. this...
Sketchucam 1.2 is now available!!! Thank you to Swarfer for all the hard work in making SketchUcam possible.
seems alright. just get the earth wiring correct (as for all CNC installations), one master earth point etc. Google it. heavier moving...
