Hello again… I’m about to rewire everything to go with the dual end stop setup.
I read the instructions and search the forum still couldn’t find the answers to my very basic questions… thus your help is highly appreciated!
This is where I am today, without the thermistor resistor T0. My assumption is that I still don’t need this with the dual end stops, right?
Now regarding the jumpers below the motor drivers. Do I need to add the same jumpers for X2 and Y2?
My motor cabling is end-to-end i.e. 4 wires from each motor to the board. Is there anything I need to change there?
Now quoting the dual end stop instructions, and again please excuse my ignorance…
The min pins are used as normal for the first stepper and the max pins are used for the second stepper on that axis (X2, Y2, Z2), still as a min. For example, X1 pairs with Xmin, X2 pairs with Xmax.
DO NOT USE THE + (positive) Terminal. S & – (signal and Negative) Only
Xmin=X1 limit switch
Xmax=X2 limit switch
Ymin=Y1 limit Switch
Ymax=Y2 Limit switch
Zmin=Touch probe. Signal pin to plate, negative to tool.
For the safest configuration the endstops should be wired in the Normally Closed position (NC), to prevent wire disconnects from damaging the machine during the homing sequence.
- I should not connect anything to the pins in the blue square
- (–) goes to common and S goes to NC or vice versa?
- starting from top we have Xmin, Xmax, Ymin, Ymax and Zmin, Zmax? That leaves the 5th and the 7th pins unwired, correct?
- For Z I see some people using an endstop switch also instead of a probe.
a. Is it possible by the firmware to only use X-Y end stops for start and place the Z axis manually?
b. When we say probe we mean something like this? https://www.amazon.com/Stylus-Machine-ToolsThread-Diameter-M4D1-0L20/dp/B07FSMMCXR/ref=sr_1_2?dchild=1&keywords=cnc+touch+probe&qid=1619545655&sr=8-2
