New project... replace theT8 leadscrew on my Ender 5.. Why? when the Z axis stepper power is lost (after finishing a print.. the bed falls to the bottom of the printer. The leadscrew is 8mm but has a 2mm four start thread! easy to move quickly but cannot stay where it is put. Got a replacement from ebay shop hereT* 2mm but a single start thread. It requires a change in the eSteps for the Z axis in the firmware but after that you're good to go. (I'm doing a YT video on it and will put a link up later. |

looking forward to the YT video. Also, weirdly, after moving the post, your link seems to just link back to this thread again.

no worries, just thought you might want to edit your post so the "here" link goes to your correct link.

update..
setting eSteps in SKR E3 V2 with TFT35
I just installed a single step leadscrew on my Ender 5 with SKR E3 V2 and TFT35 touchscreen. It is super easy and quick with the touch screen access.. even an alphanumeric text entry screen!
It was the usual problem of the bed falling when power lost to Z stepper motor.. annoying enough for me to have to do it anyway.. LOL
I did a quick YouTube video; not so much about the fitting although some things are mentioned and useful (it is a fairly straightforward job anyway) but about how to change the Z axis eSteps and where in the menus to go to and where save to eeprom afterwards..

This was the first change I made after learning how to configure and compile Marlin, My dual Z-Axis Stepper motor Printer was never calibrated. Either the right or left were not level in height after turning off the power, the right or left side lead-screw would turn and fall downwards.

You did better than me compiling.. I've but been able to do that successfully yet.
Is your printer native dual Z or redesign single?

My 3D Printers are native Dual Z
I have two purchased used, the first came with no instructions to assemble. I did find you-tube videos before actually clicking Buy it Now
My Introduction to the Twins, Blu (3DP12 - 24volt) and Red (3DP11 - 12volt)
When Purchased
The Twins Now
I have Upgraded thru most Marlin versions sense purchase, now running all 3 systems on Marlin 2.x.x. s
An found my single sheet plywood enclosure a perfect solution to ABS printing without warping, enclosure hold both 3D Printers..

Interesting project..
Looks good!
Can I ask what heated bed and surface you are using.. For non warping ABS?
I'm not getting very hard with ABS.. although I guess there are lots of varieties of filament out there..

I purchased nothing special, was told that ABS was the way to go so to test I selected the cheapest. I heard that ABS does not like breezes or cooler air near the model while printing. I decide to build a enclosure from a single sheet of plywood 4' wide X 2' High and 2' in depth. Adding a hinge to the top front of the enclosure I hung two 2' X 18" plastic sheets for a front door. I only use the Heat from hotbed to heat the enclosure, and the build surface is nothing special. I print the ABS at lower end temperature 232C and the Hotbed at 96C to help keep extreme temperature changes from causing warping
My bed area is 220mm X 270mm I cut to fit.
