 +===== Calibrate E-steps ===== 
 + 
 +Run this calibration after changing filament brands and after a nozzle swap. 
 + 
 +=== Prepare the printer === 
 + 
 +  * 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.

 +===== Loud noise when moving Z axis =====
 +
 +Colorfabb: For us changing the EEPROM speeds worked well.
 +I would suggest for both values 9mm/s. (For the Stacker at Formlab, this didn't fully get rid of the whine).
 +Of course good maintenance is very important, so lubricating the linear rails is important to prevent unnecessary friction and rust.
