Ich habe meinem Portal von GBRL und CNCJS nach linux cnc und mesa 7I76E um gerusted. Grosse vorteil wieso ich es gemacht habe is das LCNC die anlage nach Homen des Anlages immer wieder nach 90 grad sets. es functioniers super.
nach einem monat is die anlage im X/Y bereich bei mir noch immer 90 Grad.
It's just 5v going to the 7i92. There's two 5v power supplies because I didn't realize the 7i76 can get power from the 7i92. As far as I can tell the stepper pins for TB2 are the same between the 7i76 and the 7i76E correct ?
STOP !!!!. I thought you said you had a 7i76E. Your picture is of the 7i76 with a 7i92. The wiring is different.
You will want to put a 24vdc power supply in the system to power TB1 field power. DO NOT put more then
5 volts dc into TB3 logic power. On that note though you should be able to supply the 7i76 with the 5 volts
from the 7i92 DB25 connector but I don't know the exact pin out and jumper settings maybe PCW could chime
in on that one.
Some things I would caution you on one stay away from the TB6600 they are too small of a stepper drive except
for the smallest of the nema 23 stepper motors . I went with the DM556 after running into cooling problems with
the TB6600 on a 3040 router stepper motor. The TB6600 also has the cheapest and worst cooling path for
for a drive . Sometimes they use heat transfer tape and thermal grease and I had one that bareilly had any
thermal paste at all between the chip and the chunk of aluminum the manufacturer used as a thermal bridge
and the heat sink. ( it would shut down randomly due to thermal overload )
When I am setting up a screw type of machine be it leadscrew or ballnut I go with 8 microstep
With the spindle motor control it is highly dependent on what the motor driver is . If it has the usual
0 to 10 volt dc 3 wire potentiometer setup ( red, yellow, and black wires ) you can control the speed
directly with the 7i76E. Maybe add an enable relay for added safety. if the driver has a low voltage
On/Off switch ( I.E. 24 volts ) Pictures of the spindle drive will help immensely.
as far as wiring with the 7i76E the below PDF should help in your endeavor
