Lookin nice. ... I would have recommended taking it to a cheap car paint shop who has a heated shop to paint during bad weather. But hey, you needed that info 9 months ago. ... Just like me, a day late and a dollar short! ... Your build is looking good!

The last few parts have been ordered. I ordered the VFD, proximity sensors, and relays for the sensors. I will need to run power above the MM with a power drop from the ceiling and figure out a plan for dust collection. For now, I will build a dust boot and run my portable dust collector until I have something bigger and better in place. I'm getting some assistance from a relative with the mounting bracket for the spindle, the final machining on the pinions, and the flattening of the spider car. I should have those back soon. I also need to mount the control box and the VFD on the MM. I think things should start coming together. The list continues to shorten which is a good feeling. I apologize in advance for blowing the average build time out of the water. Maybe you can throw out the longest build which would be me by a mile.

Herb,
I take it you didn't get the sarcasm from my earlier post above With the passage of time comes knowledge, well at least we hope so. I see a long build as someone who is building within their constraints and making sure there are no mistakes. I am glad to see you are still at it. Keep up the good work. |

On To Wiring and Electrical
A little progress this weekend. I'm going to mount the control panel and VFD on a hinged mounting board to the main beam like Surfcnc and TechGladiator. I also installed a permanent vent on the control panel this weekend as well. Two of prox sensors are installed on the gantry and a brand new sheet of 1-1/8" thick mdf is on the cross members. It's not bolted or drilled yet. Below zero (F) temperatures are keeping me from the outside shop. I moved as much to the basement as I could.

Looking Good! Are you putting the VFD also inside a vented enclosure?. I don't think you want to have dust going into the VFD.
|

|

Yes, I plan to put it in an enclosure. That's a temporary arrangement. Any suggestions on a good panel to purchase for that purpose?

How big is your VFD? I have a few boxes (pvc) that may work as I dont use them anymore. I will just ship it to you.

That would be terrific! It is 6"W x 9"H x 7"D. I'll shoot you a private message for payment information. Thanks Miguel!

I should take a quick spin down and see your machine.
|
#101

That would be quite a spin. It looks like over 8 hours according to Google maps. I'd be happy to show you the machine when the dust starts to fly. It's getting there!

8 hrs. is just around the block for Pete.

Small task completed. I welded up the hinges to 6" x 48" 13GA sheet metal and used flat head machine screws to keep from interfering when the tubing is attached to the main beam and the panel is hanging. The top machine screws are holding the control panel at the top. That should give plenty of strength to the control panel board for years of hanging around.

Actually it would only be half that if I combined it with one of my frequent runs to Minneapolis.
I've been to Darrens a couple of times and that is much further. My cohort and #1 son Tony will be doing the muscle and brain work on this. Thought it might be nice if he actually got to see one first. Of course Darren does have his new laser engraver to look at. Decisions decisions.

I had this idea about using motorcycle air filter as vent before... thought it might look cool (or maybe just stupid). |

Hi Nikonauts - Here are some links to the manufacturer and a link to the sizing chart. The links show the two parts I bought but size it according to your panel. You can buy them online from several places including FactoryMation:

A little more progress. I'm happy to have a matching Rittal control panel for my VFD. It fits perfectly and now I can use the same cabinet key. I'll paint everything up after I punch some holes in the square mounting tube at the top and finally get it attached. More small victories.

Have you met the clearance and ventilation requirements for that VFD? They get warm, and then they get grumpy.
|
#110
|
|||
|
|||
Not yet. The vents are on the way though. If I have to put a fan in, there is plenty of room. Is it typical to do more than just vents?
|
#111
|
|||
|
|||
Depends on how hot and how dusty your environment will be. The VFD has internal fans, which will move air and dust; if your ambient temps don't get up into the sweaty zone, vents ought to work. If they do, I would consider a negative pressure fan and an intake filter. You should be able to determine this pretty quickly after an hour of operation or so. I don't mean to raise a large alarm, as long as you're thinking about ventilation, you'll work it out.

Some minor paint to touch up but I finished the hinged control panel support board. It turned out pretty nice I thought. Thanks for the great idea guys.

Herb & Sean, thanks for the links!

Today's progress. The support board is drilled, countersunk, and bolted down with carriage bolts. All 40 holes, well...39 anyway. I couldn't get at one of them. I also mounted the control panel. I'm still waiting for the other vents. They have been backordered but at least the holes are drilled and cut.

Time to run the wires. I added a PVC wire duct that measures 2"x2"x approx. 26" from McMaster. I tapped three 1/4"-20 holes for the wire duct into the gantry. I'll try and get wires started this weekend if possible. All of the cable glands are installed so it's time.

Herb,
Can you please share the length of the cables for each axis, beginning from the entry point of the cable chain? Thanks. |

I have the majority of the wires run into the cable chain over the weekend and tonight. I have two of the four motors fully wired and talking to Mach3. Two more to go and getting closer. Lots of wiring left though with e-stops and proximity sensors but I'm taking it a step at a time. Another challenge for me will the the VFD. I'll tackle that when I'm through with the rest of the wiring.
