motor is rated 100VDC 26A so no pico no mesa drives are suitable.
With a half bridge circuit (half bridge driver + 4 suitable mosfets)
i will drive it with pwm from linuxcnc.
The feedback to linuxcnc will come from linear scales each axis has.
Motor does not have encoder is is a simple large brushed DC motor
IRFP260N has
V DSS = 200V
R DS(on) = 0.04Ω
I D = 50A
Witch is ok / mosfet at saturation has 26A x 0.04Ω = 1.04V voltage drop about 27W thermal losses
of course at switching situations power losses are far more but with a good heatsink with a fan it will be ok.
These mosfets have very low RDS(on)
I think i have in my stock very low rds(on) high amperage mosfets from a spot welder project..
I have 10pcs of these

but the are 75V rated so not lucky...
@ vre
You need a H-bridge, that is not half bridge, that is a full bridge.
A half bridge can drive a motor in both directions, but only with 2 power supply voltages, so +-100 V in your case.
A full bridge is used exactly for avoiding using 2 power supply voltages, and for some other reasons.
