CR-10 Smart Hot End Kit Incompatible with Bowden Setup #3

Open maximus5684 opened 1 year ago

maximus5684 commented 1 year ago

I received my conversion kit today along with the Easy Swap kit. In the video you say that the conversion kit can be used without purchasing the LGX extruder and staying with the Bowden setup. Unfortunately, I found this not to be the case for the following reasons:

I am currently modifying my hot end/CR-Touch mount to be compatible with your part cooling fan shroud to avoid this issue. Just wanted to let you know about this problem. Other than this and a few minor screw fitment issues, the kit has been pretty good so far. Thanks!

Thanks for the heads up, I guess I under estimated the size of the original compression nut... hmm, I'll try and think of an alternate solution for that. Please send some pictures if you find a work around in the meantime, also can you elaborate on the screw fitment issue? Thanks!

edit Sorry for the brash comment before. However, I highly recommend changing out the push-in connectors.

Second note: I got a defective gantry board. One of the pins on the X Stop was not fully soldered. I have fixed mine but I thought you would want to know from a QC perspective.

Thanks again for the heads up, I'll have to inspect the solder joints on the boards. I guess I figured the professional board manufacturer would have had them 100%.

What gauge wire are you using? I had a chance to preview your comment before editing and you had mentioned the silicone jacket wire. I know that stuff can be pretty thick and I can see how that would be an issue. But I'm just wondering which components you're using that stuff for and why since the wires going to the breakout board shouldn't need the flexibility of that type of wire.

For my setup I was using pretty standard 22awg , stranded with PVC jacket without issue. For limit switches, sensors, and even the stepper motors this should be more than sufficient for the task. The heater cartridge is the only one that I would recommend something different but that's where I put the screw terminal connector for larger gauge wire and more current carrying capacity.

Let me know, thanks!

Actually, I was using the pre-terminated JST kit that you recommend. These wires are very thin, straneded wire with somewhat thicker, silicone insulation. However, I also re-used some plastic-jacketed wire from the printer and had the same issue. The problem wasn't getting the insulation in the slot, it was getting the wire in the movable opening down in the slots. It might be a tolerance issue but I had this issue on every single connector. I successfully connected about 10 wires with multiple attempts per wire before I gave up and went back to my board with soldered-on JST connectors.

Side note: I uploaded a new version of my rigid hot-end mount/BL-Touch/CR-Touch mount which is compatible with the 5015 fan part of your kit and a Bowden tube setup. https://www.printables.com/model/442914-cr-10-smart-cr-touch-and-rigid-hot-end-mount

Second side-note: I'm almost finished with a fully-tuned Klipper config for a CR-10 Smart with the same upgrades that you've done on your printer minus the direct drive extruder and the screen (I used a BTT Pi TFT43 connected to my RasPi with a CSI cable and KlipperScreen). Would you like me to make a PR on this repo for hosting that or would you like me to keep it separate?

Hey thanks, I think the challenge with the connectors is the angle of insertion and perhaps stripping the correct length from the end of the wire. I'm putting together another one right now for a CR6SE and I think I'm going to have to make a separate short video on how to do it reliably so others don't have the same issue.

As for the klipper config, maybe we should keep it separate as they are fundamentally different but I would be happy to link to your repository for those looking to go that route. What do you think?

Hey Josh I actually have a repository with a cr 10 smart klipper config. If you'd like, I can let you create a PR there and we can merge em

@blazecoding2009 I appreciate the offer but it seems like your machine has a sufficiently different setup to mine and/or the EM kit.
