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.
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.
