I've had my machine for close to 5 1/2 yrs totaling 1000 hrs. The y truck was stuck so I took this opportunity to rebuild my cut motor which has
had no rpm sensor since the very beginning.
I got my mcahine on ebay reconditioned for $1000, with no warranty.I've paid $1851.00 for parts and bits since then, so total
cost is : 2851 or at least $3000 , if i figure in bits and bearings I bought from 3rd parties. So that's less that $50.00 per month for machine, consumables and replacement parts.
to Sum up my maintenance : here is the timeline and what I went through in hrs.
20 hrs lubed shaft
40 hrs --Lubed shaft replaced Switch cover
55- replaced x gears
57 hrs replaced board sensor - measurement sensor
64 lubed shaft
87- lubed shaft
110 - lubed shaft replaced y gearbox
135 lubed shaft
149 hrs Brushes replaced,shaft oiled,dust collecter installed :
169 hrs -lubed shaft, replaced sandpaper belts
174 hrs--- replace y axis motor assembly, belt, lubed shaft
194 hrs 15min --Lubed Shaft
214 hrs - lubed shaft . Replaced z motor bearings, replaced z truck with carve tight system replaced sand paper belts with Rubber belts.
234 hrs ----9/26/11---- lubed shaft
235- replaced ffc cable, Replaced whole flex shaft ,external and spring
254--10/07/11 lubed shaft-- Installed external vacuum-trying 1/32 bit
329- oiled shaft--
470hrs - oiled shaft replaced gear and bearings in y motor pack, replaced FSC
cable, replaced board sensor, sensor cable , z motor pcb board, y truck bottom roller bearings, (2) ,Y BELT IDLE PULLYU ASEMBLY, RETAINING RING FOR 5MM EXTERNAL SHAFT. cut front rubber belt 1/4 in and moved botom plastic retainer
to keep belt from contacting the brass roller.
490 Hrs -- replaced FSC
cable,oiled shaft (having edge detection error) found out it was the y-belt retainer)
in the back -- it wasn’t seated correctly.
538 Hrs- replaced z motor bearings-- having z motor problems -- loosened and tightened z truck roller bearings. Lubed shaft.
544 hrs -- having x axis skipping problems -- found out the brass roller was not making
contact with board. Lubed shaft.
612hrs -- Checked motor brushes(will change @725Hrs ) , Lubed shaft, lubed (with white grease the lifter posts)
684Hrs -- changed y- motor pack with one I had( nylon and brass gears worn and shot) (shaft on nylon gear worn, brass gear would not engage) ... Lubed shaft , lubed posts and bearings. (put on a new Bit) Shaved off back or board sensor and changed lens on same.
701Hrs -- Changed Cut motor Brushes.
777hrs --lubed shaft--y motor pack shaft worn giving y axis stall errors.nylon gear shot . Changed y-pack motor assembly.
861 --z- stall error , z axis dissemebled and cleaned , y stall errors, y axis cleaned and lubed. lubed shaft
937hrs --Cut motor rebuilt, replaced y truck bearing lower left, checked and
replaced y bearings,checked z motor bearings. cleaned board sensor put new
lens (made from clear coke bottle).
I hope this helps someone....
