Congratulations and a nice build!! Grattis !!

Well done! I like your "hands on" dust collector - it is the same one I use:D

Look forward to seeing your number and name on the list.

Joe #53

TY all :P

I made a temp one today instead of hands on, works pretty ok :)

Soon my number will be mine!

Nice machine!! Nice Vidieo's and congrats on getting your number soon.

Cheers
Tony.

Well done Marcus! I read your thread again this morning and remembered that you had built your own CNC machine before. It will be interesting to hear your opinions on ballscrew versus rack & pinion, and any other things that you noticed so far.

Well this machine is way faster than my previous so, so far rack and pinions are the bomb. Not really much to complain about, a bit louder due to some cheap chinese rack and pinion (played with some other locally which were alot quieter and smoother) but they cost most more, but I can live with some noise when it works this great :)

Im pretty impressed with both the machine and the results it produces "out of the box" havent really had to adjust much, perfect flat cuts, no difference at all from each cut.

Have you tried any grease on the racks to see if the noise is lessened?
Nice job on the machine!

I was going to do that but forgot to get grease :)

A small test run made of some damaged MDF
http://pici.se/thumbs/t_KOpKehkow.gif

Made a mistake with Z when running the finishing (separate code) so it messed up a little but all in all, it got potential.

I would think twice about grease on the racks (dust collectors)

If there is enough dust collection that shouldnt be a problem, or if your not milling super dusty stuff like MDF.

Another Q, anyone using EMC2 and controlling their spindle via RS485 and MODBUS RTU?

Joe, the racks Frallan is using (and I) are not top notch quality and I noticed they are a bit 'sticky', a pinion doesn't run smooth over at.

Frallan, what I did is I got a bit of liquid 'sand paper', the liquid is used to sand pistons for cars and I put it on my rack and run the machine over it some time. This will 'sand' the rack/pinion to make it run more smooth. This way it made my pinion feel less 'sticky'. When I am going to get my belt reduction I will get 32tooth pinions, i think they are better, 22 is a bit to small I am afraid (or just bad quality racks, but for the price.......).

After cleaning I put a little bit of oil on the rack to make it run more smooth. After it I have been doing a MDF job without just collection (Hatchoe.......) and the racks looked just fine after it.

About spindle control, I think somebody wrote that and I have seen it on the EMC2 forum/IRC channel or mailing list. Google is your friend!

Ries, that is good info, thanks for sharing, I think we share the same supplier...

Bah logos taking longer time than expected =(
Guess Ill have to mark the machine in some other way until then

Frallan,

I printed the outline on a A4 sticker and then cut them out by hand. Took me less then a hour on the kitchen table to get it done. May be not as beautiful as printed, but at least it works. You cab also buy some cutting knives and mount it on the MM ;)

Geeez! Is this video realtime!?!?! http://www.vimeo.com/10774348 What size bit was being used? Also in the dry run and figure 8 video,... what was all the grinding noise? Other than that I cant get over how cool these things sound when operated:) After I build my MechMate Im goin to build a MechWarrior:)

its realtime, 3mm tool.
The grinding noise is due to the rack and pinion not being top notch :)
But after running some time now they sound less and less, so its just a matter of "running in".

Wow, thats awesome. I didnt think the machine could cut that fast with a bit that small.

Seems ill be getting my precious stickers tomorrow and that means a nice number!

Did some milling today which resulted in this:

Some flaws due to the fact that I dont have proper means for attaching work pieces yet, but its coming :)

HEy I read through this log and didnt see what steppers your using or is your using reduction either. Can you share? Thanks.

May I have a number please sir? :P

http://pici.se/thumbs/t_eIIbbpZAf.gif
1 on each side

http://pici.se/thumbs/t_RCQCNyCUp.gif
And 1 on each side here too, but mirrored and on the left side compared to each other.

Yup, you most certainly should be getting a number. Well done!

Congrats Frallan!

Thanks :)

Finally got to it to make a new dust shoe for the proper dust collector.

A picture with some of the parts, MDF and rubber

And a little mockup on how its supposed to be kind of.

Its a static version that you adjust to the workpiece, will be making a similar later that adjust after Z.

Congrats !!! I was out of pocket for a day or two and I seem to have missed a lot :D . Now to get the builders log updated....

Ahh ty :)
Numero 57, need to make a nice little plate to attach to the machine now :P

Congratulations dude!

Well done

Builder's Log Update
 

Frallan,

Congratulations on completing your MechMate and Serial #57.

Here is the updated Builder's Log.

Please provide the dimensions of your MechMate for the Builder's Log...either a Reply in this thread or a PM to me will work.

Also, please review your Builder's Log entry and provide any changes you want to make.

The size is 2750x1630, due to the fact I wanted to be able to get it inside too :)

Not really much to add, will be adding proper dust collection and some nice way of fastening for work pieces.

Thanks.

Updated Builder's Log is here.

Assembled and mounted the dust shoe and it works really ok, some leakage due to the skirts but I will get brushes instead, but all in all it works really good. Whole lot less of dust left :)

Frallen #57: Good job! Welcome to the club. Machine looks great and the new dust foot looks really good. Which design did you use?

Joe #53

My own design I assume :P
Might have seen similar but afaik I did it after own ideas.

But its a pretty obvious design and where to mount it :)

Nicely done Frallan, Enjoy it as much as I do, or should I say as much as we ALL do.
Dave #52

Got tired of fastening the way I used to at first so I finally got my ass up and prepared for proper ways of fastering materials. Will be leveling the table tomorrow and prepare the spoilboard for the new way :)


Meanwhile I got a nice "pendant" working via EMC2s' hal.
Cheap and works very well

That link says: "Sorry, "EMC2 gamepad pendant" was deleted at 6:00:34 Fri May 7, 2010. We have no more information about it on our mainframe or elsewhere"

Try this Gerald http://vimeo.com/11555627

Nice clear video! Thanks

Yeah for some reason 2 uploads said failed, but suddenly worked so I removed them not thinking about this link =)
