Is there a way to slow down the first fast Z home probing (
G28), without affecting the probe pull up speed, or making the pull up faster, without affecting anything else?
(Marlin/src/module/probe.cpp: // If the nozzle is well over the travel height then // move down quickly before doing the slow probe)
I have the following marlin values for increased probing reliability:
- HOMING_FEEDRATE_Z 3
- Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z
- Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2)
But my problem with the slow (but safe) probing, is that the pull up between each probing is also slow.
If I increase the
HOMING_FEEDRATE_Z to
18, and change the
Z_PROBE_SPEED_SLOW to
(Z_PROBE_SPEED_FAST / 12), then each slow probing is done with the safe slow speed, but the first G28 probing is done with the fast speed, which isn't reliable with my probe/board setup.
So, ultimately, I want to keep the reliable slow (downwards) probing with G28/29/30, but speeding up the (upwards) pull up movement between each probing.
Thank you in advance for your help.
