Mechmate build - Wexford Ireland.

Hello All
I have been reading this forum for a couple of months now and I want to say thanks to Gerald and all who post on this forum for the wealth of information you have made available.
I started the build 2 weeks ago and I am now waiting on the laser cut parts from cncbasher and the v bearing kit from superior bearings. I will get organised with the electrical side of things as I progress with the Y carriage.
Heres a few photos of the build so far. I thought that I would use my dewalt saw with a 12 inch cutting disk to do the steel cutting and all went well untill the second last cut on the 7 inch channel iron. Bye bye motor!!!! I know it wasn't built for cutting steel but I was all smiles until I burnt out the feed coil and the armature. A little over 100 euro later and its cutting "Wood" again.
Regards
Gerry

Thanks Greeny. I have the laser cut parts, the gecko g302v and the v bearings arriving next week. Time to clean the shed so I can make another mess.

Interesting way to mount your cross channel with a SHS underneath. Is that 50 x 50 SHS? Did you build the table bottoms-up?

Hello Ken. I am not sure what shs is but the cross channel is 75mm x 38mm welded to the 7inch x 4inch heavy channel I propped and clamped the steel and welded from the top. "Right side up". I hoisted it all in the air so I could weld the bottoms of the cross members and paint.
My main channel is 1/2 inch thick and very heavy. I was worried whether the roof would buckle while it was being hoisted but it was ok.
Regards
Gerry

Thanks for elaborating.

I meant Square Hollow Section = SHS.

Did you see much twisting when you hoist the table?
Did you tried hoisting one corner of the table & the leg nearest to this corner lifted before the other legs lift?

Great progress! Look your very well organised workshop.

Hello Ken. I hadn't tried it but you got me curious and as the hoist was in position I moved it to above one corner and started to lift. It was about 40 mm off the ground before the oposite side decided to lift. I could nearly use this blue lump (mechmate) as a tuning fork. If you hit it it can hold a tune for a few seconds.
Regards
Gerry

I have this info.

MotionKing 34HS9801 (490 Oz-in / 3.5N.m)--> price: $55.00/PC --> 3.0Kg

4.1mH half-coil/parallel/unipolar
50 to 65VDC --> 65VDC Max
4 Amps
WATTS = 65 Volts X 4 Amps = 260

If you purchase only the toroidal transformer, you need match to AC:
60VDC / 1.4 = 42.8VAC
WATTS = 60 volts x 16 Amps = 960
Capacitor = 4A x 80,000/42.8 = 7.476 uF --> 42.8 + 20% = 51.36 Volts

bipolar series
Dont match with the Gecko

Gerry, from the first post in this thread: Calculate the Voltage and VA size of the DC power supply for stepper motors/geckos, you will see that you need a 65V DC power supply capable of supplying 11 Amps max. (Ros forgot the 67% factor). A 60V DC supply may be easier to get and will still be quite okay.

I havn't seen anyone in Europe get these easily off-the-shelf, but I do see that MCP is starting to offer power supplies http://www.motioncontrolproducts.com...plies_v2.0.pdf
A pair of PS705 supplies could do the job. Suggest you give them a call and see if they have a bigger model yet.

Otherwise, it really isn't difficult to build your own supply: Homebuilt power supplies for GeckoDrives

Thanks Gerald and Graham. I am sorting through all the info at the moment. I hope to have the power supply sorted in the next few days. Then its time for the kitchen project. I received my laser cut parts today from cncbasher and I have to say the quality is stunning. I will post more photos very soon.
Regards
Gerry

Hello all.
I am just about to order based on the above advise for my setup a 65vdc 15 amp unregulated keling power supply. Are there any problems with this choice. Thanks Gerry
