make sure it has A+B+Z mine is single ended but differential would be nice.
.
I have put some dxf files in the zip file. on the encoder mount I used a bearing on the shaft in the mount to take any load of the encoder
The 28 tooth gear in did on the mill with a recess underneath with 6 magnets and 3 grub screws to hold it in position I also put a flange on the encoder gear as well to help to keep the belt in place.
.
I generally take the belt off when not being used.

There is a bit of test code here that worked for me:
forum.linuxcnc.org/pathpilot/34005-fitti...1100?start=50#109484
.
I used a connector off the mesa 5i25 port similar to this
Then used a 25pin cable to the control box where the 7i85s is mounted shown in a previous pic.
You will need the bit file 5i25_t2_7i85s.bit that is in the Zip file with ini and hal files

Code:
To update Tormach with a new tgp file ie 2.4.3
First copy old config folder to desktop
then update to the new file and make sure the software runs.
Log files for errors in here /home/operator/gcode/logfiles
Then follow below:-
Put this bit file 5i25_t2_7i85s.bit
in Mesa /home/operator/tmc/mesa
Copy this to tormach_mill_base.ini file
Replace the original config line with this:-
"config= num_encoders=4 num_pwmgens=1 num_3pwmgens=0 num_stepgens=5 "
BITFILE0=mesa/5i25_t2_7i85s.bit
Copy custom_encoder_ilowpass.hal to v2.4.3\configs\tormach_mill
In the tormach_mill_base.ini under {HAL] add this:-
HALFILE = custom_encoder_ilowpass.hal
From the tormach_mill_mesa.hal file comment out as below

Thank you so much Clive, I really appreciate it!! I owe you a beer! :laugh:
I saw earlier in this thread that you went form a 2000ppr encoder to 1000ppr. Any reason for that?
