video NPN 4 module realys
 

hello ken watch this video, do not know if the connection is good, help me if wrong XD

Awesome work, Hevert! I have a bit of friendly competition for next number ;)

@Ken thank Arduino's and Raspberry Pi's for those relays. They are extremely cheap and plentiful on eBay and available in 4, 8 and 16 channel versions.

:Dhi dale, and you started yours? pass me the link to see your progress and help along the way XD

Hello, I start the new MechMate. Here I will report progress
 

that would be my number MechMate? hahaha

soldier?

or screw?

I can both ways but what would be the best?

Thank you

I would weld it. Screws could come loose.

images seem to be missing.

conection splinder VFD
 

Hi guys, I need help please. I'm trying my Spindler VFD but in 400Hz max rev is 11520 rpm.

it may be happening?

so what I have connected

splinder 2.2kw

I hope you can help me thanks

thanks already fixed. I needed to configure the VFD

VFD Setup:
Change PD001 to '0' (source of run commands)
Change PD003 to 300 (main frequency - Hz)
Change PD004 to 300 (base frequency - Hz)
Change PD005 to 400 (max operating frequengy - Hz)
Change PD006 to 2.5 (intermediate frequency - Hz)
Change PD008 to 220 (max voltage - V)
Change PD009 to 15 (intermediate voltage - V)
Change PD010 to 8 (minimum voltage - V)
Change PD011 to 100 (frequency lower limit - Hz)
Change PD142 to 7 (rated motor current - Amps)
Change PD143 to 2 (motor pole number)
Change PD144 to 3000 (rated motor revolution)

Good you fixed it yourself. There's a lot to learn.
You also want to hook it (your vfd) up to a pwm signal (0-10v) card which in turn is controlled from Mach3, that way you can control your spindle speed by means of Mach3 ( so on the screen of your computer).
Otherwise you need to change speeds from your VFD directly ( which can be annoying when it's built in a box) or with a remote turnknob suited for your VFD ( Gerald used this method his first machine).

Only full speed is no fun when cutting. Different materials/cutters need different feeds and speeds.

hello looking for info fox if learned. now thanks for the recommendation, I wonder which card you recommend me to control the speed using Mach3?

Hevert, as there are just too many factors involved, such as material, tool size, tool materials, finishing requirements, hold-down methods, individual cutting habits,... etc there are really not much to recommend on speed.
You just has to experiment with them.

Hi Hevert, you need the PMDX 106 it will integrate with your PMDX122 card and provide you with PWM control of your spindle VFD. You will lose an axis though for this capability. But I assume your not going to use A or B axis so not really an issue unless you decide you want more axes. Alternatively you could just put a POT on your panel, no computer control but really simple. There's a bunch of other ways to interface with the VFD but these are the most simple. You can also click the VFD control panel out of its socket and make yourself a ribbon to remote mount the VFD panel fascia on the front of your box door. That's not a hard solution but often overlooked.

between yesterday and today was a lot of hard work, I'm slow because I work alone so I like, I'm glad I'm so nuy if the'll see running before Christmas, God willing.

I hope you like it and go away and my number MechMate lol thanks for this forum, if you would not do any of this

Looks good Hevert...keep it up, you will have a number in no time!

Hi Hevert, glad to see your progress, now you can't stop. Saludos.

Duds, friend thanks for the advice, I'll keep pending while construction progressed thanks

hello friends. Now I'm putting my MM me some errors are coming like (V Groove Guide Bearings) I buy them 3/8. I need the 12mm is that true? I need the 12mm x8? and 6 x 3/8? for Z axis

Thanks I hope you can help me greetings

Hi Hevert 12mm and 1/2" are almost identical. Remember decimal and imperial are abstract concepts you could take measurements in octal or binary or bananas if you wanted to. Get yourself some vernier calipers and measure everything you buy. Ignore the size stamped on the side of drills. Drills are whatever size your vernier says they are. Don't be afraid to ream out and re-tap nuts or threaded holes to suit you. Get yourself an engineers reference or 'black book' or print out some conversion tables and tapping clearance tables.

Also if you haven't drilled your spider yet be careful with the vague marks on the laser cut kit for the 6 z bearings. You will probably want to use the widest set of marks but use your calipers straddled between the bearings dry fit flat on your bench. Then add the 1/2" to account for your centres. Search for the thread on how to setup the spider.

Also I didn't bother to make the mounting bosses. Instead I welded in the nuts and use them for the bosses. Then I ground all the bits level with sand paper on a flat surface. This resulted in shorter bosses and I had to file back the stop tab on the spider but apart from that it all fit together well.

Hi Dale. thanks for the advice, paulo asked my friend and he said it was better to follow the plan and buy the:
14 x GW3 v-rollers
6 x B3X eccentric buching for bearing

It is an expense that would not do, but it is necessary to see my MM running. someone has more than me about the band's economic hahaha

Hi Hevert, not really advice just a way to think about going about work in general. ;) It's how I think anyway.

Anyway, what i'm really writing about is: Check out http://www.instructables.com/id/From...C-Fabrication/ there are three videos that give great insight into the workflow from design in SketchUp right through to CNC machining and assembly. It's actually the first time I have ever gone [been lead] through the process, though I imagined it would be just like it is. The production robots I have worked with are very different. I really need to learn SketchUp I can see already that CAD is going to be my weak point.

Also in the third video take particular attention at 2:20 minutes. The operator pulls a front fascia panel of a Huangyang VFD, and starts and sets the spindle speed, from under the machine table. It reminded me of your question about convenient speed control at the machine. I still think the best and easiest way is to just run a potentiometer out somewhere convenient, just three wires and you can drill a hole for the potentiometer anywhere.

Hello friend, greetings to all. This time I am writing to ask for help with the bridge, and I soldered but I am very bad LOL, I need you to give me advice what to do? if I disarmed all or folding hard?
The video is my problem please view is very short and help me please.

Hevert,

Two of the holes on Y-car are slotted to permit adjustment of the wheels. Put one wheel all way up and the other all way down and see if there is still a gap. You can elongate a little bit the slotted holes...

ahhhhhhhh perfect paulo thanks, I'll do it tomorrow
