Yes, it is.

It does have some of the original Merc parts and others were modified with the same bearing spacing. Here nor there.. that system is long gone from my machine now.

@@MrRocksalt no worries. I was trying to find a good hybrid corexy model and was glad to find yours, but then it wasn't hybrid at all. i'll keep looking...tx

A traditional 'valve', like in a motorcycle engine,is placed in that hole. The air rolls over the lip of the valve and it makes an air curtain. That air curtain travels across the plate no matter where the toolhead is. so you get dedicated nozzle cooling and some plate cooling at the same time. When the toolhead moves, that valve air is still hitting the part.

Anti-Warp drive is installed. *patent pending

No, not really. Something I have been at for the last year or so trying to improve on.

There are some other videos I made with different style ducts, fan's and my explanations in the videos for each. I started with octoduct and it brought me into designing the valve duct.

Air distribution :)

At times for nothing! Seems like 1 win, 10 losses!

Chevron Black pearl SRI. Temp, fan, tuning flow, and a good rigid X beam for corexy.

Yes, it is!

of course lmao

I will say... I pulled my .5mm smooth PEI/other side textured PEI off because the glue is lifting. Put a spare plate that is thin PEI on one side and spring steel on the other. This plate is HAH when taking off!! The other one is manageable. Seems the thinner is better for heat!

3 things.. the extra weight lowers the center of mass. The cup insulates the hotend and it also heats the air off the duct so there is less delta/worse cooling to ensure better layer bonding. The latter, just a guess.. Still testing.

I made 3 prints. 0.0, 0.01, 0.022. 0 was the worst, .022 was the second worst, and .01 was the best. Corners are sharp at 0.01. At -0.022 the corners look like over heating or some other. 0.018-0.022 was the sweet spot and now is .007-.010.

THose places have no retraction. Only at layer change. That model printed flat, so those lines on the hat are on plane with the bed.

Unfortunately, this printer was not made at one time. It is a test machine to see what works and what does not. I have a new build planned from the mods I have done to this printer. Instead of making new all the time, I re-iterate and compare. Hopefully, the lessons learned will contribute to a better printer. Thanks for your humbling words.

@@MrRocksalt hi, do you have a github or discord to follow and learn how to build a machine like that? Thank you and great work :)

I talked to Scottie in the engine room and he gave it all he could!

Hey! It's good as a stopwatch! :)

This is PEI on spring steel, held on with a magnet sheet. Description updated with machine specs.

thanks and awesome build.@@MrRocksalt

Tension has moved twice, but these are new belts and they need some running in. Observing to see if any change.

There is a .jpg in the beginning of the video/thumbnail. Pretty straightforward design, but hard to make with bought parts. Had to turn one part on a lathe to make it.

Like a guitar!

@@MrRocksalt cool! i am also working on my own cross gantry design, any tips on how to keep all the rails square?

Description changed with links to calculator

@@MrRocksalt thank you very much as usual curious about other updates on Facebook, I was happy to follow your post for the belt tensioner

Not yet. The issue is the lowest speed is not low enough. Motor needs to be hall sensor or use lower supply voltage. I have been busy with other tasks that I have not gotten back to it.

@@MrRocksalt thanks, that's a shame hope you'll have time soon. Do you think that's because of the driver not being capable or the motor not having a low start up value?

@@benclimo461 Low speed cogging is what happens when there is no feedback on rotor position. The phase angle is not optimal for torque at zero speed. So the motor needs to spin a bit to get past that. With hall sensor motor it can be spun at very low RPM. It's possible with lower supply voltage the min speed can be reduced, but less top speed. Top speed is not that much of issue as the PQ curve will drop before 100% speed. I will get back to it once I get some other things aligned.

Here is one video, there are others explaining the function. th-cam.com/video/D8_9uj437Jk/w-d-xo.html
