Some other tips while I think of them:<br>
<br>
- From the Control Panel, warm up the heater to 220C and let it sit at-temperature for a good 10 minutes before extruding anything.<br>
- This give the ABS already in the barrel time to pre-heat.<br>
- I spent time calibrating the thermistor with my thermocouple thermometer so you Do Not Want to run at higher temperatures.<br>
<br>
- When using pliers to remove plastic noodles from the nozzle tip, be careful not to squish the nozzle tube itself.<br>
<br>
- When slicing a model with SkeinFox, use the "Artengine ABS" profile I created. It has "Unproven Mesh" set and the temperatures lowered from the old 240C default to more reasonable 220C.<br>
<br>
- Models sliced with SkeinFox expect the starting nozzle tip position to be at Z=20mm<br>
1. Position the nozzle at the centre of the build surface<br>
2. Lower the nozzle tip until it just kisses the build surface<br>
3. Open the control panel and zero the coordinates<br>
4. With the Z+ control, send the nozzle to +20mm.<br>
<br>
- When you first start a print, it's ok to hand-tweak the top Z stepper pulley if the first layer looks too squashed or isn't close enough.<br>
<br>
- While you're still figuring things out, locate and keep a finger hovered over the little reset push-button on the motherboard.<br>
- It's not like a desktop computer where you need to power off gracefully to prevent data-corruption. Hit the powerbar switch if need be.<br>
