Too many hobbies, not enough time

Well nearly finished the aluminium machine - so will use it to make the jrgo that I started on earlier in this thread - It seems a real shame not to finished what I started

Hi just coming in on this thread after reading all the posts before. I was lucky enough to be given a jgro by a kind hearted sole on this forum. Just needing all the electrics, I bought and installed a 3 Nm 48v system bought from Motion Control. The one thing I was told by the person who donated the machine (which I had to deal with) and read of others having the same problem is the spread of the unsupported rails. This is a real issue with the gas pipe design and if I would change anything I would definitely use a different rail system. Some have braced across the table with long studding and packed against the sides. Using the packing blocks that came with my table, I have finally got over it by screwing one side to a wall and introducing a 2" x 2" length of angle iron down the outside edge of the other side.

Only up and running 3 days ago I would strongly recommend anyone about to use Mach 3 to watch the training videos on the Artsoft site. Oddly although mentioned that the demo version allows 1000 lines of code, I think that was with Mach 2 as my Mach 3 demo only allows 500 lines. The problem solving video shows how to calibrate your table, something I would have thought should have been in the setup video, although dead easy, make sure you watch both, it could have saved me a day of head banging

Still not cutting yet but hope to be real soon.


Also in West London (Uxbridge, Harrow area)

Thanks for the info about the videos - I have downloaded as much stuff as I can from the mach website - and will have a good watch before playing with the machine which is near completion.However may not be able to work on it for a while as moving house is in the pipeline.Once settled in the new place will strive to get my maching up and running and earning money for itself.

Well I am back, Moved house settled in, put machine back together , ran it up, now at the stage where my son and i have (we think) go the accuracy sorted out , just need to test some shapes , loaded up the road runner from mach 3 - but I believe its dimensions are in imperial and I use metric so thats no good.Anyway willl do some more testing in the morning.

[Drakkn]

Got hold of the g code for the kress mounting - loaded into mach3 and did a test run using mdf - Have a slight accuracy problem - the router mounting is made from hdpe which appears to be flexing so not producing accurate dimensions.So will now make a mounting from aluminium when I can find some.

Also need a good way of holding down the work piece - probably go woth double sided tape to start with.

Hey nearly there though - just trying to find a cad package now that is relatively easy and cheap to use. Any ideas - autocad is way too complicated for me.

[Drakkn]

Ok I finally have something to show for all my efforts and all your help on the zone.

Anyway still have some problems with flexing from the z axis which is causing dimensional problems but pleased with things so far.

More things to overcome - how to hold the work down - double sided tape ?
or build a vacuum bed ?

Oh yes and learn mach3 and turbocad

comments gratefully received.
