That attitude is good, I like positive thinking something I want to keep under all situations...I hope to keep it at my cnc building too,lol!!!

Bought a supercheap dti with magnetic base and started checking my ballscrews as Im getting some binding and wobble.
After shimming some bk/bf bearings its much better. Still get some wobble as the screws are not quite straight. Or it might be the end machining...

Im measuring about 0.2-0.4mm of wobble in the different screws. Anything to care about?

Not much done but it feels great to have mounted the spindle :)

Some questions for you all :)

Have had no time in the shed because of sick kids so no progress, only planning.
Thinking/planning the electrical stuff and think I have the normal stuff sorted out like psu and motors..

Question 1.
Enable signal to drivers.
Should you use it and why? As I understand it it's normal to skip it? Do understand that you can use it to clear driver errors if they should occur..?
If I should choose to connect them it's just 5v to ena+ and parallellconnect ena- to the enable port on the bob?

Question 2.
I have this Chinese bob

And I found a nifty schematic here on the forum. Think it was Jazz who posted it. It says how to connect the bob to the vfd to control it via software. On/off and rpm via 1-10v. Have the HY vfd so have to change parameters pd001 and pd002. It sounds good! Then I found this schematic from routercnc

Here he has buttons and relay to start/stopp and a pot for speed. This appeals to me as I love panel buttons but I want to have the software option as well :)
Is it possible to connect both kind of systems?

Question 3.
Was planning to follow a schematic from jazz for the general safety layout. Bet it's familiar to you all

Then I found this from eurican (spelling might be off here)

Here he has a switch for the limit override and a buzzer so that he doesn't forget to reset it to limits.. is this safer than the momentary switch in jazzes schematic? Or just that you don't have to hold it in while jogging off the switch?

Thank you for your thoughts :D

Will answer myself :D

Question 3, reread euricains thread and found the same discussion. (Maybe that's why I had the question from the start hehe)
So if you can reach it's better with button instead of switch so you don't forget!

Another questions for you all!

Will have my pc in my controlbox.
Is it safe/okey/good practice to use 5v from pc psu or should I use the nice chinese psu that I have bought?
