I haven’t posted for a while. I’ve had my K40 for sometime and have been doing various upgrades before I’d even turned it on ! Good news is, yesterday I powered it up and test fired and it worked (I’m amazed as it was sold on Amazon as a 40w machine, but only has the 600mm tube).
Anyway, to the point. I have a temp sensor in my coolant - and while raster engraving I watched the temperature climb to over 22c. So I bought a cooling system to put in line and a new pump (I don’t trust the chinese one). But then I thought - hey - have I bought the right pump ?
I’ve had a search on here - but couldn’t find anyone mention the L/H figure - so mine is 1500 L/H - anyone know if that’s about right ?
B.T.W. I’m going to post my Arduino Z table (and source code) soon - table is controlled by LCD screen - it’s nice - works well.
Thanks in advance.
