 ==Städning==
 Dammsug alla åtkomliga ytor, innanför drapperiet samt vid datorn.  Töm vid behov påsen till dammsugaren. Slå av 400V [[:Fil:Portalfräs manöverpanel.jpg|på manöverpanelen på fräsen]] och stäng ner datorn. Torka av skärmen och datorn med en ren och torr trasa.
+==Configuration==
+This section contains information about how the CNC router is set up and configured.
+You do not need to know this to use it, but it is useful for maintenance.
+===Spindle VFD===
+The Spindle VFD controller is a BD600 from Folinn. It supports up to 3200 Hz (despite the manual claiming only up to 600 Hz, due to export regulations) in its V/F mode. Sadly its vector control mode only seems to support up to 320 Hz (seemingly an undocumented limitation).
+The spindle itself is a '''G-penny BST2.2MC-80-24K''' spindle specced at '''380v, 2.2 kw, 5.5A, 800 Hz, 24000 rpm''' for ER20 collets.
+The BD600 VFD controller requires some configuration. Here is the one that was used during its initial set up. Note that the order of the commands is sometimes important:

 Under 2021 uppgraderades spindeln till en ny och mer kraftfull vattenkyld variant. Flera andra förbättringar gjordes också, så som att dammsugaren och spindelhastigheten kunde styras direkt från LinuxCNC.
+Under januari 2025 uppgraderades spindeln igen till en ny och mer kraftfull variant. Denna med 8 poler istället för 4, vilket gör den kraftigare vid lägre varvtal. Detta då kullagrena i spindeln från 2021 hade börjat gå sönder, och detta ledde till glapp och vibrationer. I samma veva så behövde VFDn bytas ut.
