230 plus for ABS. What you printed from Thingiverse is for PLA. I normally print at 235 with no fan(like PLA) and heat bed at 100 to 110. Settings depend on the filament also.

Thermal paste is suppose to be used to transfer heat to keep things cooler. Only that, when it dries out it can flake off onto your print.

My opinion and 50 years experience with electronics. Thermal paste is for transferring heat away to keep parts cool. At heater block temp it will dry out a lot faster. Replaced many failed transistors where the paste dried out. The gap is really same and has a very minor effect on temp. My heater blocks heat up to 240 c in 45 seconds and stays there. The thermistor is right next to the nozzle whe

Y=max probably be min and Y home direction -1. Max home position should probably be positive for both x and y.

The lcd might still be good. Pluging in the power supply without load and you get 12 volts should mean it should be good.

Cleaning the bearings will not help if the small balls are damaged. I am going to look at a V groove system.

I have the same problem with the y axis. My bearings don't last very long even with greased rods. Rod alignment is right on. I get a few excellent priints and then back to the same problem. Have to look at another method for the y axis.

Windows 10 runs fine on my desktops but not so well on my laptop. Maybe because my desktops have the pro version where laptop has the home version.

Mine is black but it is not used. The main arduino board is used for different things beside 3d printer. they have different boards that plug onto the arduino board depending on the use. they even have a bread board for development.

I didn't see any labels on your pix showing where the 12 volt and the 24v are. 12v power supply neg goes to the outside term of the 4 term green input. 12v + goes the second term from the right. That powers everything but the heat bed. Neg of 24v goes to the third term from the right. 24v + goes to fourth term. That is for the heatbed. Be sure the heatbed is 24v. Extruder heater goes to d10 on th

I looked at the spec for your kit and it states a 12v 7A dc power supply. The power supply is not big enough if you use a heated bed.

If it is a mk8 head you can search the internet for an all metal upgrade kit for mk8. I got mine for 11 dollars plus free shipping.

They sell a all metal upgrade kit for approx 10 to 12 dollars. went that route.

After g29 my head goes to center and stays there until the bed heat is right and extruder temp is right. I get the message bed is heating then heating for the extruder. It then begins to print after it meets the firmware settings. This is controlled in firmware. Sometimes I get a M105. Press the button and it starts printing. This is probally due to stopping the print and then continue.

My drivers are sdjusted to approx .65 volts on both x and y. I really had to tighten the y axis belt. I mean tight tight.

Try using a raft with bed temp of 105.

My printer is the same as yours. What material are you using? I had banding printing with .2. Went to .3 and banding was eliminated. This is with ABS at 240 degrees hot end and 105 bed temp. Also use a raft for better bottoms. Print speed is 30. Voltage on x and y drivers set at .75.

LJ12A3-4-Z/BY is a pnp sensor. You would have to change Z axis logic in marlin from true to false. Get LJ12A3-4-Z/BX which is a npn. No change in marlin. Of course you have to // the min z endstop line. Same price. Hitch + to 12 volt and minus to ground. Then feed output to a 7805 voltage regulator. Output of regulator to Z min on board. No heat sink required. Test output of sensor with metal obj
