My first post. I’m interested in the odrive because it is really cool (!!) and I like the idea of the control and silent operation.
I have a couple of questions though, while researching this forum and the documentation.
Am I correct to understand I could use a pi with Klipper to drive an SKR1.4 (for example) and instead on mounting drivers, I route a couple of wires to the Odrive to use the step / dit functionality? In that way I can use gcode and all other stuff for heaters sensors etc yet have access to a couple of Servos through the odrive? I could even (?) use 2 Servos for XY while I use steppers for the Z and E(xtrusion) on the SKR1.4?
How to connect a battery instead of the resistor for breaking? Simply connect a battery instead and that’s it? The battery should then have a voltage of (for example) 24V, so for example a Lipo s6 which would give 4V on each cell and this headroom upwards?
I’m looking at motors on HK in the range of 400 - 800 Kv, as they give a kind of size I feel sufficient for my application. But then if I use those to directly drive a pulley / belt I recon I only need like 1 to 3V? If I would drive them with 12V I would need to be very careful with the amount of Current? This is perhaps really basic question, but the funny thing is I just don’t know ;-).
I was reading the nice explanation on how to choose the servo motor. It relates to 3. Above. Is states that one computes the electric power using Imax. But how do you know Imax? From a data sheet? I would imagine that relating to 3. The current is not an issue as I’d only need 3V while using 12V?
Which control applies to the Odrive when used in Step/dir mode?
