Physical buttons to 7i96s+7i77 was created by Masiwood123
Physical buttons to 7i96s+7i77
Category: HAL
..in connection with the machine retrofit #338210
, I would like to include the hardware buttons in the configuration, also calculating the mpg. I have a lot of free inputs (all on 7i96s) and about twenty on 7i77 where I left the first three free as I understood that they are analog because of the potentiometer) now I need a suggestion, since dont have schematic for the old controller and not for the buttons, I think they are all on 24vdc including mpg. the outputs that I connected to 7i77 lit the bulbs of these buttons at 24v. should I try the configuration in terms of the mpg pendant for selector increments and mpg, and for spindle and feed override how should I connect? Thanks

Converting a Brother TC215 to LinuxCNC
Category: Milling Machines
Hello everyone,
I’ve been lucky enough to be the recipient of a Brother TC215 midway through a LinuxCNC conversion. I’ve always wanted to try my hand at CNC work, as I’ve done a little bit of manual milling and a lot of fabrication work over the years, and I’m always curious to learn and build new things. It’s been a pretty steep learning curve, as I’m new to basically all of this, but I’ve leaned a lot via search and previous forum threads and I think I’m at the point where starting a thread is worthwhile.
On the hardware side:
What I’ve got so far is: The hardware is mounted in the mill, I roughly understand how things are laid out. I feel like i have a broad sense of how this should go together, but the details are oftentimes a little more opaque than I’d like. What I’ll be doing when I have a minute :
The thing that’s blocking me right now is that I don’t really know enough to confirm that I’m wiring the servo drivers in a reasonable way. My understanding is: I should be able to wire my X / Y / Z servos in the following way, to do analog +10v control as a simple starting point. I need to set it up so I’m wiring:
My plan was to disconnect all the motors from the mill and test them on the bench, but running through LinuxCNC, so I can confirm my understanding on how LinuxCNC operates. Once the motors are confirmed to work on the bench, then I would start on wiring up the Estop, limit switches, and other things I would need to get the mill safely moving, and then follow that with wiring in the spindle.
Here's a picture of how things it sits:
Any and all feedback appreciated, as well as suggestions about if I should approach this another way. I've learned a lot here and I hope that documenting this in the long run helps someone else

On the hardware side:
- Mill is a Brother TC215
- Dyn4 AC Servo Drivers/motors
- Mesa 7i92 / 7i76 / 7i77D control boards
- HP Elite 8300 USDT running LinuxCNC / ProbeBasic
What I’ve got so far is: The hardware is mounted in the mill, I roughly understand how things are laid out. I feel like i have a broad sense of how this should go together, but the details are oftentimes a little more opaque than I’d like. What I’ll be doing when I have a minute :
- Test all my servo controllers and drives (easy to do, just need to get my windows laptop out to the mill)
- Power up the Mesa board (pretty easy, just need to spend some time looking at all the wiring and make sure I don’t fry anything)
The thing that’s blocking me right now is that I don’t really know enough to confirm that I’m wiring the servo drivers in a reasonable way. My understanding is: I should be able to wire my X / Y / Z servos in the following way, to do analog +10v control as a simple starting point. I need to set it up so I’m wiring:
- 7i77D +24v from field power to Dyn4 JP4-15 (Servo Enable)
- 7i77D TB5 (Analog Drive Interface) To Dyn4 JP4-13 (Analog +10v) & JP4-25 (Analog GND)
- 7i77D TB3 (Encoder 0-2) to Dyn4 JP5-2 through 8 (Encoder outputs)

I spent a lot of time studying the machine schematics and have a decent grasp of the workings thereof.
I removed the old Anilam GXM control, screen and manual control panel. The MESA 7i77 connected up to the encoders and I can read XYZ in the DRO screen. I can plot W in the HAL Scope, but it does not show on the DRO yet. (I think I selected encoder as rotary axis in PNCConf and will sort this out later.)
I now want to start connecting the limit switches and other IO's but have some things I am not clear on.
On the schematic attached:
D_A/18 and EXP/18 (37) would connect to V-Field on TB2
D_A/17 and EXP/17 (00) would connect to Ground on TB2
D-A/21, D-A/24, D-A/26, EXP/22 can be ignored for now. Was only pulled high to prevent fault condition for axis not in use on GXM
D-A/23 (83) is a input to indicate E-Stop active when not high.
D-A/25 (62) is a input to indicate Lubrication unit fail. (Feed Hold/ External Stop)
D-A/22 (820) is a input to indicate no axis overtravel and E-stop out.
D-A/26 (87) X Positive vector (Input)
D-A/24 (88) X Negative vector (Input)
D-A/23 (89) Y Positive vector (Input)
D-A/25 (90) Y Negative vector (Input)
D-A/19 (91) Z Positive vector (Input)
D-A/21 (92) Z Negative vector (Input)
D-A/09 (81) E-Stop Out and Reset Pressed (Input)
D-A/02 (72) M8 Coolant Off (Output, Drain)
D-A/08 (69) M5 Spindle Stop(Output, Drain)
D-A/04 (71) M7 Coolant On (Output, Drain)
D-A/12 (67) M3 Spindle Forward (Output, Drain)
D-A/10 (68) M4 Spindle Reverse (Output, Drain)
D-A/06 (70) M6 Tool Override (Output, Drain)
EXP/10 (236) "M Strobe" (Output, Drain)
EXP/20 (230) "Fin" (Output, Drain)
EXP/14 (235) "S Strobe" (Output, Drain)
EXP/06 (2311) "T Strobe" (Output, Drain)
Once I can get the limits and E-Stop circuits connected, I should be able to connect the motors and start tuning them.
Any thoughts or comments welcome.

Thanks, I'm on the way to a solution for the drivers, what's left of the cables is clear to me, and the rest are: analog +-10v signals, one 25pin input cable, which are partly connected as soon as the machine is turned on, and partly I realized which ones are for homing and for inductive sensors from the tool. and this 25 pin output cable remains, there are a total of about 10 outputs, my plan is to activate them all manually, together, by hand out of 7i77card, to see what will happen on the other side of the machine where this TB3 (see schematic) terminal block is. the cable from the pendant remained, that is, the one from external buttons to the controller, I mean jog, feed override, spindle override, axis select, step select, estop. I will have to find a way to activate the K1 switch, it turns on the drivers, but also to connect the estop to turn it off. My question is, do I need analog inputs for the pendant later, or could a configuration be made using buttons and potentiometers that would support mpg, potentiometers and buttons with digital inputs?
