Been playing around with the TIC T825 and have really been loving it. I have a few things I think could be implemented entirely in software that would expand the capabilities of this thing even further, or at least be useful for me personally.
First, a few notes about my specific context and application, so you can get a feel for my thinking. I have a relatively small motor that I am running over it’s current rating in short bursts, and then de-energizing when it’s at rest so it doesn’t get super hot. Also, my setup has a brake.
I’d love a way to de-energize the motor without putting it into an “error” state, especially where I have a brake I can rely on when it’s not moving.
it would be awesome if I could configure one of the pins on the TIC to be a “brake trigger” line that could be set to drive high or low when the motor stopped. obviously this requires separate hardware- a relay or something to actually operate the brake, but it would still be super handy to have the TIC handle the logic.
tying the above together, if there was a “motor with brake” mode for the TIC where it could set the brake trigger line and then de-energize the motor when the motor stopped, and then release the brake to move again, while not throwing itself into an error state or becoming uncertain of it’s position, that would be pretty cool.
this one’s probably less likely to see release- a mode where the TIC would automatically raise the current limit to a configurable higher value for acceleration. I’d love to be able to tell the tic to give my motor an amp during acceleration and 500ma otherwise.
would it be possible to add a mode where the step/direction pins were outputs, so it would be possible to use the tic as the interface and motion logic for acceleration, and speeds and stuff but wire it up to an external high power stepper driver.
Interested to hear your thoughts. The one’s id most like to see are 1-4. 5 was just something I thought of, not something I actually need.
Loving this driver!
