 +===== Calibrate E-steps =====
 +
 +Do this after changing filament brands and after a nozzle swap.
 +  * Remove the existing filament
 +  * Clean the feeder gears with a toothbrush or brass brush
 +  * insert new filament only a few centimeter into the Bowden tube.
 +  * Close the latch of the feeder assembly
 +  * measure 120mm of filament, from the entry point and mark with a line
 +
 +==== Connect Stacker to the computer ====
 +(Tested on 24/02/21).
 +  * Add usb-extension cables to the usb cable on the stacker, so it can reach the iMac.
 +  * Connect the usb cable to the usb hub (renkforce). It doesn't work when connecting to the keyboard, or to the iMac directly.
 +  * Open ''Repetier-host Mac''.
 +  * Go to ''printer settings'' and select the ''Stacker S4'' profile.
 +  * Check the following values:
 +    * Baud Rate: 250000
 +    * Stop Bits: 1
 +    * Parity: None
 +    * Transfer Protocol: Autodetect
 +    * Receive Cache size: 127
 +    * Timeout: 40ms
 +    * Ping-pong communication (not checked)
 +    * Firmware send OK after error (checked)
 +  * Click connect
 +  * Optionally: test the connection by enabling the fan at 100%
 +
 +
 +  * Slowly extrude 100mm of filament:
 +    * In the print panel, enable ''Heat On''. (We will not extrude filament out of the nozzle, but the extrude command only works when the nozzle is hot. This is a safety feature).
 +    * Set the extruder temperature to 200
 +    * Set the extruder speed to 60mm / min.
 +    * Set ''Extrude'' to 100mm
 +    * Click extrude
 +
 +  * Measure to the mark to find out what was actually extruded. Take 120 and subtract the measured distance to find the actual length of extruded filament.
 +    * For example, if you measure 5mm, you extruded 115mm of filament
 +
 +
 +==== Change the EEPROM Steps Per mm ====
 +  * In Repetier-Host, go to ''Printer > EEPROM Settings''
 +  * Find the entry for ''Extr.1 steps per mm''. This is the current E-Steps value.
 +  * To calculate the new E-STEPS number, use this formula: ''( 100mm ÷ How much filament was extruded) x ( Your current E-Steps ) = Your New E-Steps''.
 +  * Update this value at the ''Extr.1 steps per mm'' EEPROM entry. It's immediately stored in the printer's memory.
 +
 +Run the extrusion test again (on a new part of the filament) to see if your changes result in 100mm extrusion.
 +
 +
 +
 +
 +
 +
 +===== Pre-print checklist =====
 +  * Minimal 2 wall lines.
 +  * Check ''Z Seam Alignment'' (under Shell). Random might be nicest for objects without corners.
 +  * Is there enough filament?
 +  * Check the fan blip at the start.
