I have a cheapo 3020 router which I bought for making PCB's. It has performed really well other than the z axis coupling coming undone 3 times, and one dodgey connection. I have already made a few mods to the machine, including making and addon PCB for the control box which adds...
Limit switches with LED indication.
Home switches with LED indication.
Probe with LED indication.
EStop LED indicator.
Spindle control with 5 seconds warning buzzer.
The control box itself has 3 x Tonsen drivers and a Tonsen BOB and I am not sure if these are any better than the normal Yoocnc ones. So far I have not had any problems with the control box, but wondered if it was worth upgrading while I was doing the planned enclosure.
Here is a pic of what I had in mind...
I have already made something similar out of MDF, but it obviously makes it dark inside. The plan is to use some 20mm x 20mm aluminum extrusions to make the frame. Then I would like to use clear perspex for the top half and aluminum panels for the bottom. In the bottom part I would like to house the electronics, new or old, and add a joystick and or buttons to control the axis. The rough dimensions would be 450mm wide, 550mm deep and 500mm high. The bottom part would be around 100mm in height which is comparable to my current control box, should I wish to just simply move everything.
So I am looking for any advise on making the enclosure (I planned to get the parts from Valuframe and have been quoted £160ish for just the frame and fittings), still need to source some perspex and aluminum sheet, which I could probably get locally. Anyone used Valuframe with the no drill connectors? Any better or cheaper alternatives?
I am obviously look for some advise for the electronics as well, I have seen other people use 542H stepper drivers are these the best idea? I don't want to spend a fortune if I don't have to and also don't want to upgrade if I don't have to. As it's working ok should I keep it as it is?
Any thoughts or suggestions welcome.

As you say yourself why upgrade if it works ? it would probably make more sense to put the money into making a better machine from scratch but if you don't plan on any more demanding work why bother ?.
Regarding the enclosure, gravity makes everything go down including lubricant and swarf so I'd say it was a bad idea putting the electronics underneath. It looks like a nice tidy solution but vibration would also transfer through the components, I would suggest a separate box something like a PC tower shape.
Instead of messing about with joysticks and buttons I got one of these and it works great, assuming you use Mach3 software.

Sounds like you have it sorted, I like the idea of the down lighters.

While sat on the riverbank fishing today I had plenty of time to think about this, especially seeing as I wasn't catching much.
I thought I could dismantle the Toshiba laptop that is running Mach3 and mount it inside the top enclosure. Perhaps ripping out the Motherboard so save space if needed. This would keep some of the cables/connections inside, keeping things neat. I have a 17" Iiayma touch screen monitor that I could use in place of the laptop screen. The only potential problem I see, is the metal enclosure might inhibit the wireless signal, (I use the network to send the Eagle gcode output direct to the CNC laptop) although I am sure I could get over this.
I also decided that I should probably go for 30mm x 30mm profile and make the whole enclosure slightly bigger too.
Use some decent runners and make a drawer in the top section to house the laptop.
I really like the idea of having the laptop built in to the top housing, but I have concerns about vibration and the hard drive. As luck would have it I remember pulling 2 of these 64Gb SSD's from a dead Sony laptop.
All I need now is a msata to 2.5" IDE connector, which I have found on Ebay for £10. 64Gb will be plenty as currently it has a 40Gb IDE drive, of which I am only using 7Gb.
Not suggesting you put a bed in there but thinking about this arrangement for a top lid.
