Having difficulty setting X0Y0 for a tool sensor

having trouble trying to save a location for a new tool length sensor on my Altmill 4X4. I’ve tried every combination starting from the home position, my park position, goto prompts to no avail.

I have installed a rapid change Solo model with tool length sensor, I have set that X0Y0 location, tried everything and save every combination, watched numerou videos, but whenever I use the G01 code with coordinates and feed rate, the spindle always go to a different location.

Can anyone give me a detailed procedure on how to go to that location

@31fordtruck When you say that you have saved the XY0 position of your sensor, what have you done exactly? Since you have homing switches, it should be a simple matter to define an offset from that position to the location of your sensor.

Gwilki”: I am running Gsender version 1.5.3 with homing enabled, When I say that I have saved the location of the tool length sensor means that I just made note on paper of the X and Y coordinates of the TLS location after the spindle has left the homing position .

As an example I home the CNC, the three X,Y and Z greyed out numbers just above the blue home button now show 0.00

I now jog the spindle to the middle of the tool length sensor and make a note on paper of the X and Y digits which now show as X 22.50, Y -982.84 which is at the front of the CNC and slightly to the right.

My Z position is still at 0.00 since I did not make any change to the Z

now if I home the machine and my greyed out numbers ar all 0.00

Basically I dont know what to do from here, you mention making an offset, if so , how do I do that ?

No matter what I tell the machine to get back to the TSL it goes too far in X+ and not far enough in Y-

@31fordtruck If this were my setup, I would take those “offset” coordinates in X and Y, create a macro, and use one of the programmable buttons on the estop to run it. That way, I would home my machine, press the button and the machine would move to the sensor.
I don’t have homing/limit switches on my LM Mk1, but, to me, this is a similar concept to my using a macro to offset my cross hair laser with my router and diode laser module.
If you didn’t want to use one of the programmable buttons, you could program a keyboard shortcut to do the same thing.

PS. Unless you have experienced some issues with more recent versions of gSender, I would suggest that you update to 1.5.7.

You’ll want to do something like this

g53 g90 g21 g0 z-1 g53 g90 g21 g0 x600 y-450

The g53 command tells the processor to do the next command in machine coordinates (where home is zero zero) so the first command there raises the z axis up and the next command moves to x of 600 and y -450 in mm as G21 means in mm

I upgraded from version 1.5.3 to 1.5.7 over the weekend without saving any config data and now it works exactly as intended. I dont think it was a bug in 1.5.3, however I think over the months I may have inadvertantly changed some values in the overall config could have been the problem. right now I’m trying to create a macro to get to the tool sensor instead of just using the console but that might end up on another thread. thanks for the input guys.
