In my case the firmware it’s compiled using the property CNC=1, the file that you downloaded from the site must be enough.
Lol I just looked at my previous post and it says pregnant style LCD. I meant pendant style LCD. Predictive text will get you.
I was wondering about that…, jeje, don’t worry.
the LCD is optional in the firmware-cnc
Hello again, been busy machining bifold doors for my studio and did not want to make these changes until that was finished. Well that’s finished and would like to get this sorted and would like some assistance.
The chinese boards have arrived and I have found some things that I’m not sure about and would like to check:
The ‘Example Config Options’ on the spindle-module page states ‘spindle.rx_pin =’ and ‘spindle.tx_pin =’. If this was RS485 should they not be A and B?
The ‘Spindle.dir_pin’ where does this go? I only have A, B and GND on my board.

@Colin_Wildsmith1 Would you mind continuing this conversation in a new post on Reddit ? https://www.reddit.com/r/smoothieware/
G+ is dying soon, don’t want these conversations to die with it.
Hey Antonio, just came across this post looking for Modbud board and I was only able to find some 4 pins… and smoothie board demo has 5 pins according to this page : spindle-module [Smoothieware]
using something like you linked :
Can I just do this (not using the “DIR” PIN) ?
(smoothie <-> UART to 485)
3.3v – VCC
spindle.rx_pin P2.6 – RXD
spindle.tx_pin P2.4 – TXD
spindle.dir_pin P2.5 –
GND – GND
Yes, of course, in my case “dir” pin is not required. I suppose it could be used to enable “forward” or “backward” spindle’s direction. If you need both ways for the spindle, maybe you have to connect a button and wire to the vfd for each case. If I can remember, there are available screws on the vfd to define “forward” or “backward”. You have to use that screws and wire them to your button or buttons as you expected. By default, if you use this breakout, only a one way will be available. It depends how the spindle rotates. At the beginning of the tests using the breakout, If the “direction” that can be seen does not convince you, just exchange the “hot wires”. I can’t remember them, maybe they are labelled as “U,V,W” from the spindle to the vfd, just exchange two of them (in my case that was the solution), but, I can’t remember if it was U-W- W-U, or V-W W-V (just to give an example). Check this out and how the hot wires can be exchanged to be finally sure… hope it helps in some way… (The 4th wire (the green one as I remember) coming from the spindle is earth)…
I remember there is a program on the vfd that can define the direction of the spindle’s rotation, maybe you can wire the spindle to the vfd using u,v,w as you wish (first, validate if these entries are the hot wires), and after, change that program directly on the vfd. I could not remember the number of that program, check the vfd manual, and look for the related program and it’s possible values…
If the “dir” pin is not absolutely related with this, I don’t know which needs will require a tx-rx communications with the vfd in real time. Maybe the current rpm’s, the current consumption, or other parameters. Anyway… that breakout will not allow this case… (I suppose).

@Antonio_Hernandez Sorry, didnt got the reply notification ! I got everything hooked, but “M3 S10000” dosent do anything. Got an idea? Using the same module you listed above.
I tried to flip the RS+ and RS- and when I do, the RS485 RX/TX light are always on… so I guess it’s okay.
I don’t see the LED blinking when I send M3 or M5.
Here’s my full configuration of the VFD
Pd013=8; reset up the inverter.
Pd001=0 ; #1 Knob/Analog, #2 – RS485
Pd002=2 ; #1 Knob/Analog, #2 – RS485
Pd004=400; Base Frequency;
Pd005=400; Operating Frequency
Pd003=400; Main Frequency (need to do 4 and 5 first)
Pd008=110;Voltage to 110v
Pd011=120; Min Frequency for Air Cooled (7200RPM)
Pd014=15; 15s accell.
Pd015=15; 15s decel.
Pd041=3; 3 is suggested by the other file provided.
Pd070=1; 0-5V.
Pd072=400; Low Analog Frequency
--Non?--Pd073=120; Min Frequency for Air Cooled (7200RPM) for 0-5V PWM
Pd120=120; Stale Protection (120%).
Pd141=110; Max Voltage
Pd142=11; Spindle Max Current is 12A, but I set to 11A.
Pd143=2 ; 2 poles;
Pd144=3000 (Motor Max RPM, 24000@400Hz = 3000@50HZ)
PD163: 1 ; (Communication address: 1)
PD164: 1 ; (Communication Baud Rate: 9600)
PD165: 3 ; (Communication Data Method: 8N1 RTU)
Pd176=1

Ok. That sounds great !. Really good to see that the rs-485 module works as expected.
it’s a little offset as you said (like 7890 instant of 8000), but all good for me !
While it’s working with a minimal error over rpm’s, I would like to think… it’s alright…
