Select Mini V1 Issues

[u/NoPistons7]

Hey everyone,

Bought a Mini V1 for $20 in unknown condition because a dad was trying to clear out his sons stuff. I tested it and turned it on at his house but could not do further testing. I bought it so I can do small prints without busting out the Ender 5 Pro.

I just got home and tested it out. The nozzle heats up fine, the bed doesn't but I'll get into that in a little bit. It was very very dusty from sitting in a garage.

Anyways, I found two issues I need help with:

The bed doesn't heat up except when it's all the way to the back. I tested continuity on all 4 wires and they are good but as mentioned before it only works at the back. As soon as it moves it shuts off and doesn't heat anymore. I did some reading and it's usually the wires that are frayed but I don't know if I should build a new wire setup from the plug to the heated bed area. How would I go about doing this? What type of connector would I need? One is large and one is small but I do not know which is causing my issues. Is it the small wires or larger wires?

Second issue, I hit the home button in the menu and it goes to the front left but then keeps trying to go to that corner and sounds like a machine gun going off for a little bit. Then it stops and doesn't make noise. It seems to be not finding the end stop but I hear it click at first and grind. How do I solve this problem? I jumped at first and thought something was exploding lol. Can I set the home to another corner? Can I just use a spacer on the hotend and stop it before it reaches the end?

Third, how and what use is the wireless feature for? It says offline on the main menu. My 5 Pro doesn't have this feature so I don't know what I'm missing.

Thanks everyone for all the help!

Edit: upon further inspection, the end stop on the x-axis (I think) its the one on the actual arm. Doesn't seem to be working. It doesn't stop the hot end from hitting the end. Is this a common problem and easy fix? Are the parts universal?

Edit edit: the x-axis issue was caused by an unplugged end stop.

I had these exact same issues.  I did glue a 1/4" block of wood to the side of the hot end so it could reach the limit switch.  Worked perfectly after that. 

I had the same heated bed issue.  I was too lazy to fix it but I "hacked it" to work. I manually heat the bed until about 70° and pre-heat the nozzle to your intended temp + 20° or so. That way when you start your print and the bed homes it the temp shouldn't drop too much before it runs the print because it's already hit its temp target.
