Wink It Aint Finished Yet -The Netherlands

Years ago I wanted a Shopbot - So now I'll make a Mechmate.

Parts are arriving in The Netherlands - everyday new boxes . . .

PMDX-125 + 107 + 4x 203V
Smoothstepper
4x PK296AE - SG7,2
Proximity switches + relais + cables
3M VHB tape
BX3 and GW3X
Bearings for grinding jig
2,2KW watercooled spindle + VFD
A lot of electric parts - contractor, relais, e-stop, safety switch for VFD, cable chain, 3 & 4 core cable (all from RS-components) etc.
SchutlePro
Vcarve + Cut3D + PhotoCarve
New Mig Inverter 50-250A
Grinding disks
etc. etc.
Boxes are still arriving form all over the world

Lazercut parts pick up next week - € 290
Modula 1 rails and 36 tooth wheels are orderd.

Auto Tool Changer from Blurry Customs . . very very interesting - on my list for 2010

Only a few parts need to be sorted out and orderd:
7 core cable, bold & nuts, paint, control box, steel for frame, . . and a few electro parts I missed
Il'll order the steel for the frame and welding lessons tomorrow.

The most difficult decission was the cutting size.
Next to my own business I want to offer CNC services. So in order to get a competative edge I'll go for 325 x 207cm.

I studied the plans. I'll go for a 12V E-stop circuit. Not 230V. And will put a 3 pole swtich between the VFD and the Spindle for safety reasons.
But still need to understand the function/schematic of the 3/4 buttons on the gantry. How to programm Mach3 for my motors, Zero-plate etc.
Design a vacuum system . . .

So its time to start the Mechmate construction. Kitchen project first!!
And in the same time contact potential customers for my CNC service - design a flyer/brochure to mail in january . .

I'll report my progress (soon I hope).

Hans

That 2010 may be a good Mechmate year

It has been to quiet for a long time.
Updated my location on Google maps.

The Mechmate story continues very shortly - orderd the avenger spindle last friday. It seems I have order nr 1.
The last parts - steel and V-rails are on order . . .
Kitchen project starts this week.

December will be building time - at last.

Hans

Hoi Rik,
Hartelijk dank - het werd tijd . . . .

Ik ben jaloers op je BOB.
Die ziet er heel professioneel uit. Ik zou hem te koop aanbieden in dit forum.
Ben van origine electronicus/informaticus maar dat was heeeel lang geleden.
Je post van de bouw van jou mechmate volg ik met interesse.

Hi Rik,
Thank you - it was time . .

I am jealous of your BOB. bla bla bla.
Be carefull with flames. . . .

I will do it in english so the other exept the south african, belgian and some duchts can follow.

I am making the z axis or I can better say, make the plan for outsourcing tomorrow morning in the ching cheng street. every mechmate builder should have such a street.
I also doing the wiring at this moment.
We had a broken current line last week. The broken (head) line was touching the fence from the naburs and causes current dips and peaks. A lot of transformers didn't survive also not my computer i figured out when I wanted to look for some idees for the toolhead on the forum. my wifes laptop survived

Welding started - at last - and a Question?

At last some progress . .
Where shall I put the MM in a full workshop
Table Size: X=3050
Y = 1530 + 180mm for the Avenger ATC toolholders
Started to weld the table feet and do some measurements

Question?
I'll use V-cap Rails and mount them on a steel version of the V-Cap X-rail support 10.10.220/247
In 10 10 300 DA the Y-rail Clamp strip +11mm (10 20 235) is used to set the distance between the X Rails. In my case 2171mm.

What is the correct way?
Attached picture 10 10 300-1 or 10 10 300 V-Cap rail?

In picture 10 10 300-1 the distance M = 25mm.
In picture 10 10 300 V-Cap rail the distance M = 31mm - 6mm more than in the plans. If this is the correct way than my cross bearers 10 10 302 are 12mm to short . . .

Groetjes
Hans

Hans, I havn't got a set of drawings, so I can't check for the correct millimeters. But some comments:

The drawings were mostly done, and checked, for construction with steel rails with a "sharpened" top.

When you use a "V-Cap", it means that rollers must be set a bit narrower because the "sharp points" are narrower. (add more/thicker washers behind the rollers)

No other dimensions should change. The really important distance is to the outside of the gear racks, or to the outside of the steel rails. The gantry must fit over the steel with only a small space. If the space is too big, then the gear pinion comes off the motor shaft.

I hope this helps you understand what is happening there.

m distance

Hans,
I checked my one and the drawings, try to keep distance M 25 millimeter. If you keep 31 mm your rail is coming more to the outer side of the c channel. You have to bold the rail to the C channel, if you keep the distance 31 mm you holes are coming closer to the radius in you c channel. drilling and taping holes in the radius is harder. I think you can still weld the cross bearers to the C channel without any problem with the length you have. I use bolds to fix the cross bearers to the c channel instead of welding.

I first fixed my y cart, measured the distance between the v grooves of the v wheels, and then set the distance of the v rail

a full workshop????? but it is a nice workshop

succes ermee
Rik

Sparks are flying - frame nearly ready

Update -
Frame is welded, 90% finished, just want to add 4 corner brace assembly to ensure it stays square when turned over.

Gantry drilling & welding is next.

Table on its feet

The table is on its feet now.
It was not square so I used a long pipeclamp to get it perfect.

Discovered that the top surface of the beams are not flat/90°
So I will use shims and a metal filler (rock solid after it dries) to get the V-cap rails in the right angle.

The rails beams are being drilled by an other beast . .

Gantry is next.

What software are you using? I had something similar happen while cutting a 3d file and found by changing-up the tool path configuration by a little fixed the problem. I was using Vectric Aspire 4.0 at the time but since have upgraded.

Hans, after looking back on your thread I noticed you are cutting something, does that mean that you did not sell your MM? If not, you should post a video of it operating along with the Mechmate logo to get your serial number.

You might try changing the tool path a little first. It looks like you're close though!

Same thing happened to me, cut fine then went wrong. Just change one thing or maybe two, feed rate, spindle speed, anything. Recalculate and save. The file may be corrupted. If that doesn't work then lets take a closer look at other aspects. I also noticed that if you load mach3 and turn on the mm at the same time you will have errors. Turn one on, wait, then turn on the other. That is usually the cause for any unusual activity (at least for me)

Thought your machine was long sold. I've been thinking about building a MechMate as well in the Netherlands, might happen in the future. I will be following this tread! I hope you can figure out the problem.

Check your pinions where they attach to the motor/gearbox, its probably the pinions on the X-axis.

IF you are using your smoothstepper then its a faulty drive or a wire to the steppers less likely something loose because it progresses in one direction?

if using parallel port check the computer or lower mach3 pulsing frequency
