Error Message on the Ultimaker 2+ (1) Read: "X or Y switch broken"

1) Pressed "Home Head" under advanced settings to determine the source of the problem.

2) Stepper Motor ground as it tried to continue to move the printhead

3) Turned off the machine, checked to see if the X and Y switches were being activated when the printhead reached "home"

4) Once the switches were verified to be mechanically activated, the print-head was moved to the bottom right corner of the machine. Pressed "Home Head" and held each of the switches to determine if they halted the movement of the printhead.

5) The x-axis movement ceased but the y-axis continued to jog.

6) This indicated that the error was caused by the Y switch

7) Disconnected the printer from power and un-screwed the Y switch

8) Mechanically everything seemed to be in order so we grabbed a Multimeter to test the switch

9) There was no distinction between when the switch was pressed and when it wasn't (OL both ways)

10) Unsecured the two electrical connections and saw that one of the wires had broken off

11) Grabbed the sautering gun and sautered it to its connection

12) Checked the other connection and saw that it was in need of the same operation

13) checked the resistance across and saw that it was zero

14) resecured the left switch to the Ultimaker 2+

15) tested to see if "Home Head" worked

16) Everything back in order


Laser Printer produced flames, indicating that the compressed air "Air Assist Feature" isn't properly working -Check to see if PSI is around 30 -Hook up

Ultimaker 2+ (3) print failed mid-way through: -Appeared to be an extrusion problem -Filament connection was still intact in the rear of the machine -Reversed material, saw that the filament was grinding and had gotten stuck -Cut off the spoiled filament and reloaded it into the machine -Saw a small blockage in the printhead nozzle -extruded a little extra of the filament from its chamber and forced it down to push through the blockage -blockage cleared easily and I extruded another five or so rotations to make sure all was good.


Color Mapping -Ensure to check the "Air Assist" box when color mapping. Otherwise, no smoke will blow from the nozzle and flames will occur

Ultimaker 2+ (1) Print wasn't extruding -After fixing the X and Y switch, a print was started that didn't extrude -heated the nozzle and wasn't able to move the material -checked in the back and saw that the filament had snapped because there wasn't much filament left in the spool -attempted to reverse but there was no movement -used pliers to remove the filament from its housing -put in a new spool of filament and loaded it into the system -prints like a charm

Taz Lulzbot Fix Up -noticed that it was in its home position which is touching the buildplate. As a result, the printhead was crusted over and had to be popped off of the buildplate -filament had broken near the spool, I heated it up to 215 and removed it. -Loaded up some new filament and ran a calibration print -Everything looked good from the calibration print -Ran the calibration print with the other type of filament (red) and achieved the same results

Birch Plywood 1/8": Laser 1, 9 speed, 100 power cut all the way through a living hinge and some other intricate cuts

Chair fix up -several chairs have been stuck in the down position and would drop once you sat in them -took them apart to see what was occurring -the lever that triggers the hydraulic press was being activated at all times. -because of this, weight would always push it down -took the cylinder (with the help of a mallet) out of the chair and attached some shims on either side -put it back in, secured it, and they work like a charm

CNC (1 hour) -started off running it at 6000 RPM because I forgot to check SPEEDS AND FEEDS -hit the E-stop immediately -rotated the E-stop button and pressed the green button to fire it back up -cut at 2500 RPM, 20 thou cuts, 8% (11.2), from 4.00 inches to 3.60 inches. -some very fine chips were created, almost like fluff. Probably from the backcut when moving in one direction
