Re: The Palette (Mosaic Manufacturing)

I bit the bullet with the sale going on now. http://www.sublimelayers.com/2017/06/mo ... egins.html

I'm going to set it up between my Rostock Max V3 (highly modified) and the D300VS so I can use either or to print. I am getting a second encoder to make this painlessly easy.

Re: mhackney's Real V3 Build Thread

That doesn't make sense - if you were simply hitting the bed hold downs and nothing else, reducing the probe radius should not cause the fans to interfere.

I'll try to post a photo. I have a mess here and that printer is on the floor under another printer!

Re: mhackney's Real V3 Build Thread

1) You can change the calibration points and David has a calculator on his web site that generates the g-code for you. Sounds like you are probing at too large a radius. 2) Yes they are, I didn't intend to use the blue clamps as I find them too flexible. I use a small strip of aluminum. A simple pri...

Re: Yet another Duet-to-HE280 accelerometer probe adapter

Honestly, it is not worth the time and aggravation trying to get this to work. It is almost certain that the issue is the adapter is not seeing the trigger event due to the wide variability in probing conditions. This is why I abandoned this approach.

Re: Yet another Duet-to-HE280 accelerometer probe adapter

This is one of the main reasons I stopped supporting this. It is too dependent on surface hardness for my requirements and several other factors affect sensitivity that don't cause a problem with FSRs.

Re: Hardened Steel Hobbed Drive Roller?

I've run 20+ spools of CF (not fiberglass) PETG and PLA with no issues on the Bondtech QR extruder. It's - push on both sides of the filament - design is much better for flexibles and abrasive filaments like these.

Re: PEI Print Surface How To - recap

I still don't know how to reconcile claims that "brand X PEI" doesn't work as well. I have PEI from every vendor I know about on 20+ different printers and I've never had one that doesn't work well AFTER a good cleaning and light sanding.

Even the thin stuff is fine, it works well.

See Delta Arm Joint Musings for the whole story. I respectfully submit that magnetic ball arms - like all mechanical joint solutions - are a tradeoff. I have 1000s of hours of experience with them and all the others in my post above so, much like that insurance commercial, "I know a thing or tw...

Re: PEI Print Surface How To - recap

PLA - 60°C first layer and then 55°C for the rest of print
ABS - 75°C for all layers
PETG - 70°C for all layers

And DeltaCon is right on - let the bed come up to temp and equilibrate for at least 10 minutes at temps below 60° and much longer for higher temps.

Re: A question of smell

My hypothesis is the Prometheus stinks. But really, the only thing that could cause a smell is melt temperature OR the length of the melt zone and it's ability to outgas to the atmosphere. I suspect that even though you measured the same temp, it probably isn't. What kind of probe are you using? You...

No multi extrusion is "simple" and only you can determine if it is "worth it" or not! If you have a legitimate problem you need to solve and multi extrusion is the solution, then it can be made to work. I can't speak for Repetier on RAMBo though as I have very little experience w...

Re: Dual Extrusion

Yes. I used the 713Maker effector and Chimera mount. You should be able to config Repetier and RAMBo but my experience is with Duet and RepRapFirmware. I've also done the Kracken on a Rostock V1 - that was quite the experience.

Re: Aero Mount

Having already designed a mount for the Rostock MAX for both the Titan Aero and Bondtech BMG systems, I'll say: 1 - When adding that much weight to the effector, does it matter in a practical sense whether it is above or below the effector. Since the weight is at the end of an arm, it seems like pla...

Given your other post about the bed heating as soon as you power up, I recommend you go through ALL the wiring carefully again. As they say in Tuscatillo "Somthin' ain't right."
