			== How do I make this head work again? ==

			There are several things that might be wrong, so here's the full list:

			=== Ensure there is Power ===

			Do other heads work in this tool position? Does this head work in other tool positions?

			If the problem is with this tool position, you probably have a blown 4 Amp fuse - see '''[https://hyrel3d.com/wiki/index.php/How_do_I...#Why_doesn.27t_one_tool_position_work.3F these instructions]'''.


			If the problem is with the head, read on...

			=== Seat the Head ===

			The heads won't work unless all 16 pins on the connector on the head controller are properly seated into the connector on the yoke.

			# With the head unloaded, loosen the two screws on the back by about 90-180 degrees - just enough to be able to wiggle the circuit board.
			# Push your emergency stop in, load the head as far down as it will go, and then tighten the thumbscrew (or, on Hydras, the set screw with the 3mm hex driver - called a thumbscrew hereafter).
			# Now seat the circuit board so that it makes full contact along the entire connector; improper seating may turn the LEDs on without providing power.
			# Seat the spacer board all the way down, and tighten the screws.

			=== Flash the Firmware ===

			Sometimes the head can lose part of its firmware, so let's reload that with '''[https://hyrel3d.com/wiki/index.php/Firmware#Head_.2F_Bed_Firmware these instructions]'''.

			=== Store the Head Settings ===

			Sometimes the head can lose some of its settings, so let's reload them with '''[https://hyrel3d.com/wiki/index.php/Firmware#Head_.2F_Bed_Settings these instructions]'''.

What Maintenance Should I Do?

			== Why does my bed or head read 1024°C? ==

			Well, when we flash the head (or bed) controller settings, the type of RTD is not updated.

			Pleae go into the head (or bed) controller settings, change all RTD types to "1k_PLAT" or "1k_PRTD" (depends on your version), and then flash the settings to the device with a right-click, "flash head settings", and click OK.

			Click "reset" in the upper right of Repetrel if needed; your device should now be reporting the proper temperature.

			NOTE: If you have an ESR or 30M, the '''BED''' RTD types should be set to "50K". Also, a few heads from 2015 and earlier may have a different type - please try each one until you find the one that works.

			== Why does my ESR/30M Bed read 426C? ==

			If you have an ESR or 30M from 2020 or earlier, and we have sent you a new replacement hotbed (in 2021 or later), that printer and hotbed now have a resistor mismatch. GET WITH US and we'll walk you through fixing this.

			==Why doesn't my 30M or ESR bed heat up?==

			If you're on a 30M or an ESR, then the red LED on the bed should light up any time we send (heating) current to the bed. If it does not, then there is a bad fuse or a bad connection.

			The 15A fuse is located inside the X-arm:

			[[File:Xbed_fuse_15a.png\|250px]]

			Check for 12V from ground to each side of this fuse.

			No 12V anywhere? The primary fuse on the spine has probably blown, or there is a bad connection.

			12V on one side, but not the other? This fuse has blown.

			12V on both sides? The fuse is fine, but you have a bad connection between here and the hotbed itself.

			Email us if you need help.

			== Why is my head/bed flashing red? ==

			All units should be upgraded to the latest version when it is available. If you run a head with v2 settings on a v3 or later install, the background will FLASH RED; this DOES NOT mean that you need to flash new FIRMWARE - this DOES mean that you need to flash new VALUES to the head. Please make the changes noted for each head and right-click-flash these values on your heads as shown in '''[[Firmware#Head_.2F_Bed_Settings\|these instructions]]'''.

	If you slice your STL and get "NAN" errors, these mean "Not A Number", and mean that your STL file wasn't completely manifold - the software could not determine, logically, the division between "solid" and "void" space. This is often caused when software intended for rendering things on-screen lack the precision to model for additive manufacturing. Many times this can be corrected by using MeshLab (or another program) and healing the model - ensuring that all the intersections for the triangular mesh of the STL line up, forming an "air tight" mesh. See https://www.youtube.com/watch?v=eLGIRAgLz4w for instructions.

			== How do I get rid of an M660 setting? ==

			If you accidentally run an EHR gcode on another model, and you've stored the M660 Z offset, then just change the H1 (or whichever you set) to 0, run it again to invoke it and set it to 0, and then just don't invoke any H offset values, since they are only used on the EHR.

			== How do I dispense a Specific Amount? ==

			Because sometimes folks just want to dispense a set number of microliters.

			Remember, the links on the left can take you to frequently-sought pages.

			=== Dispense 1000 uL ===

			To dispense 1,000 uL, you can press the "Dispense 1000 ul" button on the OverRides page:

			[[File:OverRides-2022.png\|100px]]

			But if that's not working... read on.

			=== Prime (some) uL ===

			Another option: you can read the Pulses/ul value (in this case, 65) and put it times (however many uL you want) in the Steps field of the Prime page (where 3000 is shown here) and then click "PRIME NOW!!!":

			[[File:Prime-2022.png\|100px]]

			=== M722 (Prime) ===

			Another option: you can get your values like above, but go to the Aux Editor > AUX EDITOR tab and type the M722 (Prime) command in: '''M722 E65000 T12 I1''' and then execute it with a right click:

			[[File:Send-M722.png\|600px]]

			For more about this command, see [[Gcode#M722_Set_Prime_Values]]

			=== M723 (Manual Extrusion) ===

			Another option: you can get your values like above, but go to the Aux Editor > AUX EDITOR tab and type the M723 (Manual Extrusion) command in: '''M723 E65000 T12''' and then execute it with a right click:

			[[File:Send-M723.png\|600px]]

			For more about this command, see Gcode#M723_Set_Manual_Flow

			== How do I run a different language? ==

			<span style="color: red;">'''YOU DON'T - IT WILL BREAK REPETREL!'''</span> You can change the language of repetrel, but if you operate the computer on another language the "," and "." will be wrong and nothing will work. Trust me.


			== How do I set Z-zero on Multiple Heads? ==

			Please watch this video: https://www.youtube.com/watch?v=IQscrgv6uaQ

			If you still have questions, contact Davo.

			== How do I change the home location? ==

			You don't. The X and Y home positions are X0 and Y0, and are determined by sensors. But you can apply an offset. See G54-59 on the [[Gcode]] page.

			Note, on the EHR there is a Z home sensor, which is at Z120. To set Z offsets on the EHR, see M660 on the [[Gcode]] page.

			== How do I change the park location? ==

			Note, if you set park for head 4, then head 2 will be 70mm off. Each position is 35 mm from the next. 70 mm between first and second slots on ESR/30M.

			1. Load the head you want to set this for in the slot you want to set it for.

			2. Record the absolute X and Y positions:

			[[File:Abs-pos.png\|250px]]

			3. Open Settings > Printer:

			[[File:Settings-printer.png\|250px]]

			4. Enter the recorded X and Y values:

			[[File:Park-pos.png\|250px]]

			5. Click "Flash Motion Settings", then "Apply", then "OK":

			== How do I change the Baud Rate? ==

			So, on (roughly) version 4.2.4x (aka 42.4x) or later, you can actually set Repetrel AND the printer to use a Baud rate of 115,200 (versus the default 38,400) - but you have to set this on the printer as well as in Repetrel:

			* On the right side of the program , go to Interface > COM
			* Select the rate you want to change to (115,200)
			* HOLD THE SHIFT KEY and click "Apply"

			You should now be connected at the new rate.
