My Cheapo Chineese 3020t mini CNC Build (more like improvements) leanring all the way

[Doddy]

Just had a quick read, ive now changed the motor speeds in my planet software from 500 to 200

seems to have sorted it i think, bloody slow now though lol

Sorry, missed that you was using Planet CNC software. Check this out http://forum.planet-cnc.com/viewtopic.php?f=5&t=1271 (no promises!)

managed to speed up the motors to 500, but changed the blend value to 0. Machining fine now, but a bit stop start on curves

not much of an update but ive begun sourcing parts for the new extraction system and also the new enclosure. Ive tidied up my tool bench and moved it from the back wall against my booth which has free'd up some more space. Also got a big screen dedicated to the cnc stuff







I have made some small holes for the machine wires to drop neatly through the base of the enclosure so it is nice and neat, will be going to screwfix later to pick up some odds and sods for the extraction system. Im happy with the setup so far :-)

small update with the new setup, extraction system is all done, just sorting the power supply to the rear fans, I bought a transformer but its ac - ac instead of dc so need to get another one then that will be able to power the fans via a variable speed controller. small progress but starting to look the part

Hi there mate, good progress! Interesting extraction, are you expecting to blow down the duct? Might be more effective to suck through the duct? Anyway assuming your Fans are 12v then something like this will work fine:

Hello Alex,

thanks for the positive comments, I will be using the rear fans to just encourage the dust from the carbon fibre (as thats what I will mostly be machining) towards that duct, that duct is connected to a industrial extractor which is housed underneath the cnc machine, that cupboard underneath has been insulated with carpet to help reduce noise. I currently have a power control box I am making for the spindle, so was installing a transformer within that to keep everything neat, im just going to tap off the 240v incoming supply to the spindle power pack then run that through a transformer then to the fan controller. Will find a pic now

here you can see the control power box im making, and also the adjustable fan controller, i bought a transformer this weekend but its ac not dc so buying another one which will hopefully sort it out. This is all a trial and I have no idea how it will perform, even if it doesn't do much the fans have led's on them so its disco time in the enclosure lol

Well ive finally got my cnc setup to a level I am happy with, had a lot of issues the past week. Firstly the pc fans I got of ebay were very cool with the led's but they were piss poor at moving air so I ended up ripping a few pc's apart to get some much more powerful fans.

To power the fans I got a laptop power pack and started stripping it back, I replaced the kettle plug with wires to be hard wired into the 240 supply to the spindle power pack.




The output to the fans was controlled via a small toggle switch. I then secured the powerpack with hot glue onto the main power pack. I have got another fan to aid cooling within this box but I was very surprised as to how not hot the box gets so I dont think there is any need for an additional fan, will see how it goes. I also wired in a controller for the spindle

here is how the box looks all back together, considering I did next to no electronics stuff before I started this thread im pretty happy with what ive done
