Being pretty new to all this CNC stuff I wish I had bought a machine to refit or built my own machine 5 years ago, well longer than that really lol. I've got an industrial unit so I have placed it in a spot where I can get round it & it has enough space to allow me to fit a full size sheet on for cutting should I need to because it's not going to get moved about lol
I can see from the solid construction of my machine why people in the sign industry thought they were so good, don't think the machine I bought originally to try & repair had done a great deal of work in it's life to be honest, it really was in good condition but then maybe the layers of caked on cutting fluid mixed with aluminium swarf & sawdust helped protect it lol.
Having read your post about the time spent diagnosing & fixing electrical problems maybe it is just as well I couldn't find any technical info on the machine & was talked into refitting it. My only concern is that the gantry height might be a bit low & if this were the case then I would look at ways to raise it a bit rather than part with the machine.
Still has the original motors fitted at the moment but I have some nema 23 3.1nm motors that will get fitted once it is up & running, need the machine to make the adapter plate so the motors fit as originals are nema 34 & frame size is different. Once the motors are fitted then the 70v power supply will go in & I will then get much better performance from the AM882 drivers that are fitted.
I had the electronics already because I was collecting parts to build a machine when this one came up but I would probably have got round to fitting something like that anyway, might just have taken a bit longer lol. The porter cable spindle was suppose to work when I got it but it didn't & when I stripped it it was pretty bad. With spares for it being almost impossible to obtain the machine now has a Chinese 2.2kw spindle fitted which will be quieter than the porter cable if nothing else lol.
