small issue with my new SD4 - Z offset thumbwheel (Page 1 of 2)

well, they did something with it. the power supply was shipped inside the unit & the bubble warp around it was scorched & melted where it was touching the bed.

.... what zip ties?

Same. They didn't do this on all models.

OP, take a pair of needle nose pliers and bend your z offset switch upwards. This was my problem and I didn't figure it out until I sent support a video of my machine as it homed. You should be able to use the stock screw. I use it on my printer with a sheet of glass on the bed. It IS long enough. Just pick an arbitrary Z offset position (after you bend the switch) and balance the bed to where you need. You'll probably never touch your z offset screw after this. Haven't moved mine in months.

All of your other solutions will work, but try bending the switch first. It fixed ALL of my problems. Occam's razor.

In the case of my machine, they did do a test print, but they shipped it with Z homed, which, over a long enough time, will bend your z switch down. Never leave your machine homed for an extended period, powered on or not. If you are seeing the screw literally "jump" upwards when you home, you need to bend the switch upward.

Also, once you get to calibrating, please post your results. I found that my machine was perfectly calibrated. No need to change extruder steps per mm, no need to adjust extrusion multiplier from 0.6, nothing... All I've ever had to do is bend that switch, tighten belts and balance the bed.

There is absolutely no problem with bending the limit switch.

Here's is what a depressed z switch looks like. This is the video I sent Solidoodle support.

I found your email address by looking up your order. I've replied to every single one of your emails. If you didn't get them, check your spam folder I guess.

See the reply icon on the left? Please don't accuse me of things that aren't true.

You can't get needle nose pliers on the base. I guess you're right. "It doesn't matter where you bend it within the range of which it can be bent with normal tools". Better?

Add me to the list of users that won't bother helping you from here on out. Best of luck in your endeavors.

Haha you deleted the thread! This is rich. Let me see if its in my history.

Found it in Google cache:

I'll screenshot it here in case you find a way to delete Google's cache too. It was a thread in the Filastruder subforum, so naturally I read it.

This has been incredible. First you make accusations, I prove you wrong. Then you make more accusations, and go and try to delete the evidence.

Unreal.

This is hardly respectful or productive.
Please stop. PM Tim if you would like, but this will in no way help the community on any thread.

Wouldn't be a bad idea. Folks are more than welcome to copy the video I posted and use it as a reference for what the Z switch should *not* look like.
