I bought an old Pacer compact 800+ cnc router on ebay some time ago, only to discover that it is made of MDF.

I am thinking of putting it back into commission, but would like some advice as to wether it is worth it.

The gantry sides seem to be MDF about 34mm thick with an inset area housing a metal plate which holds the ballscrew(20mm) and the two unsupported rails(30mm).the distance between these rails is 200mm and the gantry side spacing is 1050mm. The gantry sides are joined by
a 20mm thick top rail, and another that runs across under the machine bed.

The Z carriage assembly is aluminium and looks to be quite substantial.

The other axis seams to be quite well supported on linear rails with a 20mm ballscrew down the centre.

I had intended to make sure that every thing was tightly fixed and simply replace the electronics, but after reading comments on this site
about unsupported rails and flimsy gantries would like further advice.

The materials I cut are mainly MDF, plywood, PCB material and some plastics, so no metals or anything too hard.

I make dollshouses and miniatures on my other router (converted pcb machine, very heavy and robust), but the 800x800 bed on the pacer
would be so much better for some things than my existing 540x450.

Any comments would be much appreciated, even if a bit derogatory!!!

Thankyou, G.
