[QUESTION]MAX Y Travel reduced from stock in firmware #10

Closed BladerunnerxRC closed 1 year ago

BladerunnerxRC commented 1 year ago

Why is Y-axis max travel reduced from 212.5mm to 206.5mm?

I find that there is actually at least 5-6mm of additional bed travel in the Y-axis.

Stock is: // Travel limits after homing

define X_MAX_POS 255

define X_MIN_POS 0

define Y_MAX_POS 212.5

define Y_MIN_POS -4 //orig -4

define Z_MAX_POS 210

define Z_MIN_POS 0.15

Bondtech's Shortcut Mosquito for Prusa is: // Travel limits after homing

define X_MAX_POS 255

define X_MIN_POS 0

define Y_MAX_POS 206.5

define Y_MIN_POS -4 //orig -4

define Z_MAX_POS 210

define Z_MIN_POS 0.15

Is this a mistake? Unless I am mistaken, I have not seen any statement that indicated a loss in Y-axis travel with the LGX Shortcut Mosquito.

I am referring to this Bondtech-LGX-Shortcut-MK3S-16-EINSy10a-Mosquito.h and the other shortcut variants

LOl... I figgured it out.. I see why the Y MAX Travels was set to 206.5, It is because the PINDA will hit the plate alighnment posts on the heatbed. I removed the posts. Changed the Y_MAX to 112.5 (I saw this value in Prusa's stock firmware) I also tried a version set to 210. I can't see where is makes a difference.

I am satisfied that I can now print my 210x210 part
