Frame Built and Painted now Electrics time !!! - Cha-Am Thailand
 

Hello all
My name is Stein-Erik and I’m from Norway but live now in Thailand
Have read in this forum for over a year now but still not sure on everything involved to finish the maschine,hope i can ask if i get in trouble
Started my first cnc machine last year and now I’m starting on the MM
Table: 3000x2000 mm
4 motor: OM PK 299-F4.5A Unipoler?
Spindle: china 2,2kw with HY 02D223B VFD
waiting for the laser part made in Thailand, this have been my biggest problem to find a company for making the laser part but now i found it. The steel was also difficult to find the right dimension so for x beam i have 200x80x8cm
for the table i have 78x40x5 and the y car 98x48x2.2cm
have the most of cables and electric but cannot find a toroid transformer so i have to find a regular on but not sure what type,
so far i have cut the most of the steel and working on howe to build the control box ,have no date for finishing the machine but will work on it as a daily basic if I’m not on a motorbike trip or cooling down at the pool or have trips around Thailand. For over a year now i have been to china Town in Bankok
looking for parts in the town that never sleep and that is fun and luckily i have manage to find the most of the part for the machine and cheap too.

Oops tried to upload some picks but i cant find ut hove

Welcome to the club.
You can use E-I core tranny, or any type of core for the matter. just stick to the same specification. I'm sure you can get them custom wound in Bangkok too.

Thanks for that yes iv seen in bankok but at that time i look for toroid tr, is the spec the same as 25x25v?

I think so, Voltage depends on motor phase inductance & your motor driver max voltage capacity. I'm not familiar with OM motor, I'm using 86HS9801 chinese motor w/o the gear head.
The are more then enough info here, use the search button & keep reading.

Welcome Selbuss!

thank you Heat
and thaks to Gerald and all of the proffs at this forum that have get me addicted to this, please dont comment my bad enlish if i type somthing wrong

i talk to the company that sells rack and piniong and they sad that a 24 teeht gear have a pitch diam. of 24mm and the rach teeth to teeth is 3mm on ther modul 1 is this rigth?

Module 1 means 3.14mm between middle of teeth slope so its simply teeth distance. and yes its ok

Thank you for quick reply Danilo
Then i can order my racks and piniongs today, i go for one set of 24 teeth and one set of 30 teeth i plan to build a gearbox 3.3:1 and have a 60 teeth gear and a 18 gear teeth give me a holding torque of 2046 if my calc are rigth and wierd my motors half coil unipoler with a transformer 35VAC,800VA if this is to mutch i hope somone can correct me

35VAC will give you after capacitor and rectifier an 49.5V DC if my calculation is correct,

OM PK 299-F4.5A have 2.5mH inductance and if you calculate 32*sqrt(2.5) its 50Volts maximum, I would run them a little lower if possible.

Someone using PK 299-F4.5A would give a better opinion, or just search the forum there are plenty of posts about power supply

ok so if i go for antec 220v,, 25+25v it will give me 39V rectified

i try to figure out what bob i need some say the the PMDX-122 is the safest and i look at the PMDX-125 with Geko drive 203V becaus i want to have 4 axes at the end of building my machine any coments on that?

now i have order the bob and drivers from Steve
also order the rack and piniongs
for my machine i need 9mbut the company says that they only have 4pcs of 2000x15x15mm
but they have plenty of 1000x12x12mm so i order what they have on 15x15mm and one met of 12x12mm for the z slide or i have to wait for 6mnds. hope that i can use the 12x12mm
and to day i found my toroidal transformer and they promis i have it in one week and it is 10 mm shorter than the spec on AN-8225
The cabelchain i order take abouth 4 weeks to arrived and the brand name is KODUCT 40x25mm inside

Something looks wrong with the water connections to that spindle - like someone cut them off. Is it obvious to you how to connect hoses to the spindle?

I assumed he photo'd and worded it like that because of the bad fittings there. I hate when expensive things come obviously defective. Maybe an easy out and some new fittings will take care of it quickly.

Selbuss, is that how you planned to cut all your steel? You must be a real tough guy! With the nerve of steel & armored skin! Those Muitai practice sessions sure pays off!

hi brad the water connection var broken when i get it grom the mail and now i have new connectors on the way and have taken out the rest of the treads standing in the spindel

hi Ken
yes this is the way i do it and im nearly finish cutting the steel,its not like the rest of the world to get tools easy here in thailand,took me over a year to find a company making my laserpart and when i find it i have to explain for them in details hove to do so now im vaiting for the finish part to arrived but its not so expensive so if the parts not correct i let dem make new parts

Show us what you are hiding under that car-cover.

Look HOT.

I was just thinkin the same thing !! What you hiding under the cover?

this is not a MM its My Monster
 

The first 2 picks is from des 2009
and the last picks is from jan 2010 and now im waiting for my new engine and transmissin fro USA, i order a 650 HP bluprinted engine W/TH700 4 speed transmissin from Engine factory in usa so hopefully i resived my new engine and TH700 soon

Hi Selbus,

Welcome to the den. i think you have a BBB already :). Good luck on your endeavor.

Vishnu

I like I like.. Thanks for sharing

An amazing amount of "MechMate blue" in all the pictures above! :D

Nice wheels, does Thailand charge tax based on the size of the size of the engine? In Taiwan, we would have to pay a king's ransom annually to keep plates on a beauty like that. Looks like you are off to a good start. Good luck with you build!

hi David
the tax is only 10% of the invoice
here is a pic of the engine

A littel updat from Thailand
 

have now finisk nearly all steelwork on the machine and start on the electronic.....:confused:
here are som photos:

set up VFD
 

The electronick give me a little challange and i hope some at the forum can help me out,
i have the PMDX-122 and geckos G203V PK299-F4a motors,china spindel and VFD,but i will try to use the PMDX-125,Smootstepper,PMDX-107 and PMDX-108 input and i am not shure that i understand hove to connect the VFD to PMDX-107 so if anyone can look at my attacted DXF file i be happy,
Thanks in advanse

some more photos

wow,

Thats what i like to call beautiful mechmate blue :D

Keep those pics coming. . .

do some progres to day on the rest of the parts to be painted, but the paint i put on before the weekend sems to have somting like a cracing so i have to take all the paint off and repaint all, have talk to the store where i get the paint
and they will come and look at it, i think it can be that it is to hot to paint here now the tempratur is nearly 40 degreas at daytime, but this i told the stor when i bay the paint and they sad is was ok,
so to morrow i know what they think of the situasion in the mean time i work on the electronic and i have to addmit that ive bin addicted to the work at the hossmachine webside:Hoss Machine and the stuff he have done with his milling machine, so that i will try to build in to my MM too. That is because my MM is built for fun and a project for me as retierd.:)

Hi Selbuss

Nice progress.

Have you tried to connect your VFD with your PMDX-107 with success ?
I'm trying to make mine work with a USB to RS485 cable with no luck so far.

Sergio

Hi Sergio
No i have not connect i yet, want to be shure that i do it rigth before i connect it so i read the forum tracing if i can find somthing that make me shure, and i have not find new fittings for the watercooling yet so before i have that i will not do anything with the spindel, in the mean time i hope to find the rigth diagram for the electric,hope you get your spindel working soon :D

Selbuss, our climate is similar. There maybe 2 possble cause of your paint problem. 1stly, direct sunlight, this can bring the temp of the steel to over 90C even with ambient temp of 35~38C. 2ndly moisture, there can be 2 sources, from your compressor or from the atmosphere. If you have wet compressed air, its easy to solve by adding a moisture filter for your compress air line. Atmospheric humidity can be tricky if left unchecked, especially if you paint after a heavy down pour or leaving wet paint overnight in the outdoor. I don't know if you experience this, no doubt that ambient temperature at night is about 28~31C around this time of the year. but it can get as low as 25C in the dawn. Some times you get dew in the morning & can be quiet heavy at times.
One has to time one's painting schedule to go with the nature.
I prefer to start painting 2~3 hours before noon or after the dew are gone, apply the 1st coat & keep the job under shade until its dry to touch then apply the 2nd coat & leave to dry under shade before dust. Leaving it over night in the outdoor for further curing would not be a problem this way. As for me, I painted & cured mine indoors as I did had some space for that.

Hi Ken
Thanks for the advice
but i have clean air from the compressor and no direkt sunligth, the people from the paint shop com and look at paint and they say that it was wrong thinner for the paint so they will cost the repanting

Ouch... wrong tthinner.. who would thought of that...
BTW, found your gas spring yet?

not find the gas spring yet but i will try to find some at the lokal car dealers

testing HY VDF need help
 

can i test the VFD without the spindel connected ?
i have smootstepper and PMDX 125+ PMDX 107 speedcontrol,, have not get the waterpump for the spindell yet so i dont want to connect i before i have the pump

Hi Selbuss

Yes you can test the VFD without the spindle connected to it.
You can also connect the spindle without the water cooling circuit to it, as long as you keep it running for short periods (no more than 2-3 minutes).
