This goes for other pins as well this would permit users to adjust there board to there needs.
It's their, not there.
Just saying.

I do not understand what your saying/asking? Others reading this may agree..?
A recap, I'm suggesting to the designer of the RPI cnc hat to look at a re-design to the code to make it easy for people to re-assign pins so that instead of being hard coded to be a single correct but fixed code function input or output like PWM or a logic HI/LO they can adjust the ladder logic so the board works with there setup. Not everyone for example has a speed control able spindle but rather have a router connected to a relay for ON/OFF, a lot easier then having to manually turn the router on because they cant gcode it to cycle on or off because they dont have a PWM interpreter

I was just saying that you used the incorrect spelling of the word "their".
You used "there", when refering to people, it should be "their".

You also used it here in your latest reply.
ladder logic so the board works with there setup.
No biggy, I just notice things like that.
Maybe I have OCD. :)

I too just got a 2.6o CNC hat and have been working through the setup. I would echo a couple of the items that have been mentioned. Having jumpers for the A output slave settings would be great.

A couple of new items that would be nice to haves:

1. Option to power the Raspberry Pi from the motor supply rail
1a. An option to enable/disable supply to motor rail post supplying a DC to DC converter for the RPi power
2. LED on the motor supply rail to quickly see if power is applied
3. Header for a cooling fan off the motor supply rail (maybe PWN control from the I2C interface)

attiny85 are great if you want to add a nice PWM temp sensing control with options.... just a thought.... I'm writing code currently that will use an attiny85, read a single AIR temp finned thermistor. Control my cnc control box fan speed, it will also read the RPM of the fan. It outputs a bit banged serial for a serial monitor. It saves error status to the eeprom if any. when I get the code worked it I want to be able to adjust settings via the serial termianl. the attiny is also the last leg in my ladder logic kill switch system. depending on what jumper I set on my main logic board for safety. Triggering a kill switch, will ether kill the power supply or kill the motor enables. and both mods send an estop signal.... The only code I dont have working is the serial monitor and the ablity to adjust values on the fly.

They can be bought from seeedStudio..
Search for them here: https://www.seeedstudio.com/opl.html

@berin

Is this correct part number. SKU 320110030
All I get is this : Your search did not match any results.

Just tried it without the SKU and got this:

Connector 320110030 TAIFENG 1125S-SMT-4P SMD Grove Female Header-Beige;4P-2.0

Is this the one you mean?

Yes... I just entered "320110030"

I will be upfront, these connectors are hard to source.

What would your thought be on me replacing them with standard headers that can be solder if needed like the button header I have for GRBL?

(GROVE 2MM 4PIN CONN 10PACK) 1597-1082-ND 1597-1083-ND one is the vertical and the other is the 90 degree version. These are from digikey. these are 100% compatible with the grove connector for the I2C on the RPI hat. And they are sold from digikey in packs of 10 for $1.5 USD
JUST REMEMBER these are 2mm not 2.5mm like standard PERF board. they will fit standard perf board but you have to bend the pins a little.

StuartB does this help?
