Yes, I also think that this slider thing _should_ work differently, but since I have no idea, how to fix that, I do not complain - I am sure that there are more important issues for devs to solve. Other than that, I do not understand, what kind of effect did You expect :) Hmm yet another thing to control such 3D printer would be custom HAL component: If You need extruder input to be proportional to tool's velocity in XY plane, then You can easily calculate it: 1) use axis.n.joint-vel-cmd pins to get requested velocity along X and Y 2) get total velocity with squareroot from sum of both squares: total_vel = sqrt(x_vel^2 + y_vel^2) So HAL component should have 3 inputs: x velocity, y-velocity and enable (most probably from motion.spindle-on, because I still think that using spindle-related pins as much as possible to control any kind of instrument is the way to go, because use M3/M5 commands are so much used to). And 1 output: If enable = false, then output = 0 If enable = true, output = total_vel * proportion Proportion - some value, which would make the output correct for a given velocity. And then some copying from "oneshot" component should be done to have negative output for a given period of time on the falling edge "motion.spindle-on" pin. But since You are saying that there are CAM tools to prepare specific g-code for 3D printers, I suspect that this idea is not going to be very appreciated.
