Home Max Distance not working???

albertzerok_SW · January 1, 2017, 3:04pm

When homing a very large printer (Z 850mm), the arms only go up about 80% of the way then slow down, go up a bit, down a bit and back up a bit, then stop, about 300-400mm from the top. I’ve tried

alpha_max_travel 0
beta_max_travel 0
gama_max_travel 0

and

alpha_max_travel 1700
beta_max_travel 1700
gama_max_travel 1700

even 2000 and 10000, all the same problem.

Makes me wonder if there is a hard coded limit to the Z height, or if the z_height isn’t being recognized in the config or if there is a hard set limit in the code?

Definately looks like the default is hard coded at 500, wonder if it’s an issue with something in my config preventing ti from working.

from endstops.cpp
// used to set maximum movement on homing, set by alpha_max_travel if defined
hinfo.max_travel= THEKERNEL->config->value(checksums[i][MAX_TRAVEL])->by_default(500)->as_number();

Yep, spelled GAMMA wrong, so gama_max_travel instead of GAMMA_max_travel made the 500 default kick in.

Problem resolved
