The 3D Potter guys would probably enjoy free advertising (not affiliated with them, but I know they use duet+expansion).

Their stuff is definitely on the weird end of the spectrum, but I'm curious to see what else is posted here.

@tletourneau

A Hypercube is just one specific printer design that uses the CoreXY kinematics/belt layout. There are many others such as:
-Voron
-V-King
-D-Bot
-V-Core
-RailCore II
-Hypercube Evolution
-Many other lesser known printers

Just some food for your thought, another open source project has implemented RS485 communication to spindles in a CNC controller called the CNC xPro v5. RRF is definitely better developed overall, and it could be very powerful to port that feature. I am guessing your daughter board would be using a MAX485 style uart to RS485? I have one of those modules and could test if you were to implement it.

This is a board I have that I am planning on hooking up to a spare UART: UART to RS485 Board

The CNC xPRO V5 has a list of spindles that they have already integrated and you would be able to use those for references in your implementation (src/spindles folder). Obviously an RRF implementation would allow for the interface of way more than VFDs, and I think if done right could make it a very capable tool for more industrial hardware.

@avdoverflow I think the proper solution is to make a change to the interface to allow the commands to be buffered such that any commands in the buffer that are non motion commands could be executed on the fly/mid move? dc42 will need to confirm the possibility of this. I am very excited to see move segmentation added, does this mean that it will be possible to track the distance to go until the end of a move in DWC? If so that makes it one of the last fundamental features of a fully formed cnc controller.

@skivvy I would change that to, a restaurant with a menu of the length of a Bible that has the 8 items you want, but they are all scattered amongst it's many pages, and it takes a while to get your order, and you don't know if those are actually the right items, and if they aren't cooked right, you have to go back to the restaurant supply company to fix it rather than have the sheff fix it...

Reprapfirmware is like a buffet that's cooked perfectly has everything you need to customize right in front of you.

Just wanted to make sure you know about this printer: https://www.projectr3d.com/shop/p/daedalus

It checks all of your boxes and is ready to go!

I want one

Your only option, that won't cause issues with your thermocouple readings is to put an inline thermocouple connector.

These connectors can be purchased from Omega Engineering here:
Miniature Size Thermocouple Connectors

Make sure to select type K, with the IEC color code.

I would put the splice pretty close to the extruder, that way you can run the extension cable the whole way and have the connector accessible if you ever need to work on the hotend.

You can find thermocouple extension wire here:
Thermocouple Extension Wire
Or Here:
Stranded K-type Thermocouple Wire AWG 24 with Kapton Insulation Extension 5 yard

I know it's probably more than you were planning on spending, but if you want to use a thermocouple, then it's kinda your only option unfortunately.

I just thought I would bring/post about a connector I found that Molex makes that I think would work well for hotend connections, as well as elsewhere on my printer. What does everyone prefer to use for their hotend heater thermistor, and fan connections out by the extruder? I know the Voron guys like the microfit 3.0, and Lulzbot had the normal dupont style pins, some people use JST on daughter boards.

Molex makes some crimpable wire to wire connectors that are kinda cool (available on digikey). They call them ditto connectors since there is only one kind of crimp and one kind of housing (no male and female, but insertion is one way). Here's a video: https://www.youtube.com/watch?v=R-sWcdPl7Dc

They make 2.5mm pitch connectors, so pretty compact for what they are: https://www.digikey.com/en/products/detail/0368770004/WM10902-ND/5114214?itemSeq=354314114

Any thoughts? Is there any connector that is ideal that I just haven't heard about?

Thanks in advance.

Then you could point that to a gcode file with M25 in it.
