LinuxCNC 2.8 DM542T drivers Mesa 7i96 controller

there is a Configuration TOOL for the 7i96
just search for it

Also, I don't know anything about HAL, MESAFLASH or what I need to "talk" to the motors. I have one motor connected to one of the drivers to see if I can make it move but I get lost in what needs to happen next. I reloaded Mint 19.2 and the RT Kernel and LINUXCNC 2.8. What do I need to do now? PNCCONF? Install something from the mesa 7i96 zip folder that I downloaded? Any help is appreciated

If you have LinuxCNC 2.8 you should be able to run pncconf to create a hal/ini file for the 7I96, that's all that is needed besides setting up your PCs Ethernet port.

Ok, I have read the LinuxCNC Documentation paper (skipping the not applicable parts) through the initial setup. I was able to get my X,Y and Z drivers to turn the motor! I can't set the Dir hold and Dir setup higher than 10000. I am not using a spindle so a lot of the instructions are N/A for me. I am using regular lead screws that have 2 turns per inch but how do i get the motor steps per rev? I don't see it on the motor specs page. When tuning the motor I manually advanced it and counted 50 steps but I don't know if it's tied to the settings that I had put in or if that is the actual steps. How do I figure the settings for the drivers? I have 23HS45-3504S motors that are 3.5 amp, 1.8 degree motors. The drivers came set at 1.0 amp peak and 8 microstep/ 1600 steps/rev. Is that dependant on the motor?

Most ( I wont say all ) steppers are 1.8 degree per step, which equates to 200 steps per revolution. The microstepping is something you can choose, all it does is increases the steps per revolution. ie 2 microstepping gives 400 steps per rev, 4 microstepping gives 800 steps per rev and so on.
The electrical characteristics are dependant on the motor. Like I said before one can not expect the driver to be setup for the motor, even if purchased from the same source.
2 turns per inch seems very high, could you please check and confirm that is the case.

Set the drivers for 3.5amp or closest to it without going over.

Thank you, this is very helpful. I will read more on microstepping to better understand that setting.

Here is what the manufacturer (Mcmaster-Carr) has for the lead screw:
Component Lead Screw
Thread Type Acme
Threading Fully Threaded
Thread Direction Right Hand
Material 1018 Carbon Steel
Thread Size 1/2"-10
Length 6 ft.
Number of Thread Starts 5
Speed Ratio 5:1
Travel Distance per Turn 0.5"
Accuracy for Travel Distance per Turn ±0.009" per ft.
Thread Fit Class 2C
Hardness Brinell 126
Tensile Strength 64,000 psi
System of Measurement Inch

Travel distance per turn = .5 inch, so it would be 2 turns per inch, correct?

Thank you for your input. I will hopefully get my control box finished soon so I can get everything connected and tested.

Yep you're on right that one, any reason for such high lead ?

What kind of machine are you building ?

The frame is a Garageworx 4x4. I picked it up new-in-the-box from the original owner who didn't set it up. The kit came with these screws.

Oh ok, fair enough.
