Re: First dual extrusion print from a Cyclops hot end and BondTech QR extruders

Can you post your config.h file so we can take a look. It sounds like a misconfiguration issue.

Re: Taz 4.1 Ground issues?

It's does seem to be an issue with the 5 too as there are no design changes that would affect grounding.

You can read my solution above which has worked great.

Re: Install your own PEI tutorial

@paulmorley silicone is a common lubricant and notorious for causing issues with adhesives and paint. But I think we found the smoking gun - goo be gone. Great stuff but a bugger to remove all traces. Acetone works well though and if used sparingly will not harm PEI (i.e. don't soak the PEI in aceto...

Re: Install your own PEI tutorial

I agree with piercet, that is very unusual. What is your bed temperature when this happens? It's either the 468MP or something on the surface of the PEI. You *did* remove the plastic protective sheet right? Just kidding, I'm sure you did. This could be silicone contamination, iPropylAlcohol is not e...

Re: Install your own PEI tutorial

I have 7 printers with PEI beds. Not one has developed air pockets or started to come off. I print almost every day for at least 5 hours - i.e. a lot of bed heating and printing. I suspect it is a result of initial installation. Make sure to really bond the PEI to the tape.

Re: Taz 4.1 Ground issues?

Thanks. I use the same t nuts. I added my display so it isn't the lulzbot version so I can get all 8 corners.

I believe the taz 4 case is plastic but I'm not home so I can't check.

Re: Taz 4.1 Ground issues?

I like stiff frames. Do you have a link to the braces? As for grounding, I don't have an issue with the cross pieces and verticals on one face (front or back) of the frame. The issue was that he front frame is isolated from the back frame. These are separated by printed parts so no metal-to-metal co...

Re: Taz 4.1 Ground issues?

Although that is a good solution it is more work and expense than needed. The jumpers are secure and even if one failed it would not be a problem since I tested with one successfully.
