He claims the 5:1 pulley reduction to the drag of the z motor is more than sufficient to hold the x-gantry up. The printer was on display at ERRF ( see videos on youtube) and it indeed was stationary with no power applied.
He designed this printer to run at high speeds and admits that it is over-built, but the proof is in the prints. That thing produces some of the nicest prints I have eve

You might find some good ideas for a belted Z from this build. I'm intrigued by his 5:1 pulley reduction versus a worm gear box for the Z axis.

I will let you know. I'm fairly confident that they will work as it is the same worm gear set that is used in the V-King CoreXY, which has been built successfully by quite a few people.
One thing that puzzles me about the "layer height = multiple of native step" (aka Magic Numbers) is the effect that baby-stepping to adjust the Z offset has on the layers landing on a full step. I have alway

Thanks for the response DD. I've read your blog on your less-than-successful attempt at a cheap replacement for the Rino and I learned a lot from it. I'm sourcing my gears from Misumi so I'm hoping for better results.
Does micro-stepping increase the resolution of an axis or is it best practice to calculate using the native stepper resolution?

I'm pondering a belted Z-axis conversion for my Ender3 but I'm unsure of what max mm/step I should be targeting. I've seen designs that use worm gear setups ranging from 20:1 to 40:1. The mm/step for 20-tooth GT2 on 1.8deg stepper is 0.2mm if I'm not mistaken. Why does the resolution need to be so much higher for the Z than the X and Y axes?

Hello folks. I have an Ender 3 to which I've added a second Z-axis lead screw with the two lead screws coupled together at the top with a 6mm GT2 belt across the top ends, driven by the Z-stepper at the bottom end of the original Z-axis lead screw. I would like to decouple the lead screw from the stepper and I'm considering two options:
1) Slide the motor over, add a bearing support to the bot

Never mind, I missed the obvious. It's the z-seam.
I thought I'd give slic3r PE a try and I've had some promising results but I can't seem to get this particular issue resolved. I'm getting these weird double-bulging corners where a 45deg sloped face intersects a vertical face, but, as you can see, not on the corner adjacent to the hole in that face and also not at the lower vertical face corn

In Marlin 2.0, where is the code that controls printer kinematic behavior when a print is stopped? I want to see if I can modify more to my liking.

I figured out the problem. On recommendation from a YouTube video, I had my Servo_Delay set at 100mS...too short. It looks like 200mS is the minimum needed for this type of servo. Oh, the hours I've spent trying to figure this one out and it was so simple.

I have installed a servo deployed Z-probe on my MKS GEN L upgraded Ender 3 (for Auto Bed Leveling) and it's working great EXCEPT when DEACTIVATE_SERVOS_AFTER_MOVE is enabled. With that enabled the probe does not deploy for Auto Home and the nozzle crashes into the bed. If I use my finger to trigger the probe switch and let it complete Auto Home, the probe will deploy when Auto Bed level is run.
