Iv just bought another EC500 to convert to Remora firmware. I have a cnc mill converted with a breakout parallel board and axis GUI.

I'm going to replace the BOB and convert it to the EC500. Will Remora firmware work with the probe basic gui?

 

The (active low) analog enable on the 7I78 is
DB25 pin 6 (7I78 manual) = GPIO50 on that firmware.

So the hal file needs:

setp hm2_7i95.0.gpio.050.is_output
setp hm2_7i95.0.gpio.050.invert_output
net spindle-on => hm2_7i95.0.gpio.050.out

likewise, the direction pin is GPIO 51 so:

setp hm2_7i95.0.gpio.051.is_output
and GPIO 51 needs to be netted to the spindle direction signal
(and may need inversion depending on how it controls the VFD)

Its probably arguable that the firmware should have PWM enable
rather than GPIO control the 7I78s analog enable pin...

 

I saw your Amazon review and tracked you down here, What is the little cheap controller that you were able to make work with the axis?

Edit: for those from the future

Hi a beginner question. So I setup my cnc and I want to do a first test run. I use freecad as CAD and CAM programm. In freecad I set my origin on one of the upper corners. Then I create the toolpath. But I get exceeding limit error in linuxcnc. My machine limits are x-10  to 2000, y-10 to 1000 and z0 to -150. So my procedure is I move the tip of the endmill to the corner of the workpiece. Which is lets say in machine coordinates at x100 y100 and z-20. Then I send g10 l2 p1 x0 y0 z0. My understanding was that this sets the coordinate system 1 to zero. Then I start my program which begins with

But I get an error at G0 Z6.000 already. So what am I missing here? In machine coordinates I would still have the space to move 6mm up.

Thank you.

It all does happen fast, you'll see i had to move X (joint 0) way out so I could observe Z (joint 3) which errors out at 0.114

I swore i tried inverting that sign because i had the same idea. However, it didn't change the z motor going in the wrong direction after. I will try again here in an hour or so and update. 

Also reading 6.3 here (linuxcnc.org/docs/2.7/html/config/ini-homing.html) that value must be positive. Even though it didn't throw an error when i tried. I imagine it just take the absolute value of that number? It seems like i have to invert almost everything.

Thank you @onceloved !
It turned out to be a wiring issue

Also, if you are not using the analog output, a 7I96 will replace a 7I96S

I came this far, but getting no readings on 7i78 SPINDLE OUT terminal (SPINDLE- is GND and SPINDLE+ is +10V, both from VFD)
