Cutting Wind Turbine Blades! #38 - Parnu, Estonia

After reading this forum trough couple times i started to build my MechMate too.
Cutting area will be ca 3400*2100. It will be with big indexer something like that yellow maschine picture in this thread : http://www.mechmate.com/forums/showthread.php?t=314
Now is all steel arrived and some welding job done. Motors, gears, gear racks, and rollers arrived. Tomorrow should be here smoothstepper board and breakout boards. Spindle, VFD, drivers and cable chains are ordered.
One motor isnt missing its on turner who makes on gears shaft and key holes
Some pictures too:

Good luck with the build of your MM, but don't let the restoration of the motorbikes take a dip...Otherwise send them to me and I will work on them.

This bike isnt Ural its K-750. Badly i must sell both bikes to complete MechMate. Sad, but sometimes need set prioritys.

Started to cut down rails. I made skate from piece of MDF, but looks that it isnt very good idea burr is abrasive and it goes too quick thinner. Today gonna think something else out
Good news are that smoothstepper and breakout boards arrived.

Interesting table design. You rectangle you have on the right side, is that for an indexer?

Make it out of 2 C channels with a space in between where you can tighten the movable end,

For now car and cantry are rolling and im starting tomorrow rebolt it and painting.
Making indexer base of 2 C channels is bad idea for me because its very hard find those what are ideally straight and have both sides 90 degree angles. But i have one idea. I thougt put on both sides on indexer valley 60*40 rectangular tubes and on them MDF strips. Then i surface them with MM and i get ideal staight base for plate what has on it holding centre for indexer job. And if MDF wears down too much its easy replace it too. What do you guys thinh about that idea??
Some pictures too.

Just another idea. Is any disadvantages to use as limit switches hall effect sensors? They are a lot cheaper than proximity sensors.

One of the guys here built a Mechmate for indexer work and he used hall effect sensors. Check out Art's site Turning Around

For Hall efffect sensors, you need to mount magnets as the targets. That means that you will not be able to detect if the gantry or y-car jumps off the rails.

Using MDF strips, that are cut with the machine, before further assembly is probably a good idea. But I don't quite understand your description and sketch to see the purpose of this strip?

Gerald, purpose of those strips is get ideally base for plate what holds centre of woodpiece i havent now time to make better sketch. But on that i havent thought that proxymity sensor can "see" this too if car or cantry jumps. Look like proximity sensor 1:0 hall effect sensor

Meanwhile its starting to get blue. Its industrial epoxy paint. I hope it will last long. But damn its a messy job.

Nice….
I also like V-much you’re little brace design for your valley bracing. It’s very inspiring as I too am in the progress with my build ( kitchen project only at this time but….soon on the metal part !).
Best of luck

Tulevikus kindlasti on plaan selline sinine koll ehitada, kuid rahakott ja aeg seavad hetkel omad piirangud. Hetke plaan on teha üks väiksem ja lihtsam, et selle cnc värigindusega tutvust teha ja praeguseks hetkeks olen hästi väheke mänginud juba linuxipõhise "EMC2" kontrolltarkvaraga ja paari CAD rakendusega.
Kas sa saad ütelda kui palju sul praeguse hetkeni on raha läniud erinevatele komponentidele ja mis tööga muul ajal tegeled :P ?

Raha on praeguseks kulutatud ca 60-70K asja päris valmis saamiseks tuleb veel investeerida ca 30K. Kindlasti saab odavamalt aga plaanis on teha masin mis hakkab tööle iga päev, niiet komponentide valikul olen lähtunud pigem vastupidavuse printsiibist kui odavusest.
Juhtprogrammi valikul soovitan vaadata Mach3 poole.

üks asi mis tulevaste cnc projektide juures kindel on emc2, see vist rohkem maitse asi(mulle lihtsalt meeldib avatud tarkvara) .
Kas sa kasutad/hakkad kasutama spetsiaalseid lineraalrlaagreid või tavalisele kuullaagrile peal tehtud hülsse?

A quick translation for those who cant understand estonian wery well :

: Yupee estonian are in the game, good luck and other wishes
---------------
Thanks, i allso need a a lot of money in your wallet , do you plan building one yourself?
-------------
in the future I definitely plan building one, time and money make teir limitis at the moment, th eplan is to make a smaller and cheaper one to familiarize myself with cnc. i have played with EMC2 a little and wit some cad applications. Can you tell me how much have you spent on components?
-------------
Money has been spent about 60 000-70 000 EEK, and to finish ity up another 30k is needed. I have preferred quality over price.
as the motion controll software i would reccomend MACH3.
-----
One thing with future cnc projects is certaint that they will be driven by EMC2, its mo a matter of taste(i do like open source).
Are you going to use special v-bearing or sleeves over normal bearings?
