G64 Px.xxx sometime its call constant velocity, other times  its called path following. Play with Px.xxx to ach ieve the smoothness you desire. for graphic stuff,  dimension is alway not important.
G61 is exact stop, i.e. it will pass through the poin ts exactly and it will stop as corners if the cond ition requires eg, 120 degree u turn sharp c orner.
If G64 Px.xx wasn't there in your g-code, most lik ely G61 (exct stop) was there.

this the suspect font?

Gerald D Mon 11 May 2015 23:06

It is the default Verdana font, but from Ken's foreign keyboard setting (Malaysia).

Ken, do you use a different keyboard when you get the strange font?

Just a guess on my part, but it looks like he was set up to use a double-byte-character set, normal in many areas where more pictographic characters are used, rather than even the extended arabic characters used in most English language.

KenC Tue 12 May 2015 20:55

From what you suspected, it seem like my pinyin entry (Chinese character entry) is causing the problem.

I'll dig further the next time it happens.

Thanks

Had a rush job to get out for a commercial contractor....20 wall appliques..18 pcs. 64.25"x16",2 pcs. 70.75x16"...out of 7 sheets of 3/4" MDF.
1/4" 2 flute downspiral, 10k RPM 120 IPM federate.

Lots of cutouts...

All in all, exactly what the machine was designed for.

Jason Marsha Mon 18 May 2015 04:40

Sweet.

How many passes? or did you cut the full 3/4" in one pass.

Jason

Wall appliques, is that a fancy word windows ?:D

A good looking product.
Lots of cutouts to clutter up the shop.

darren salyer Mon 18 May 2015 06:00

1/4" cutter, 3 passes. The Milwaukee router doesn't have the brawn for a single pass.
I like to limit cutter depth to equal or less than diameter.
Just what works well for me.
120 little blocks to clutter the dumpster today, Al.

hennie Mon 18 May 2015 23:41

Those clutter looks like name boards for a primary school.

darren salyer Tue 19 May 2015 06:19

I actually kept 60 of them at the last minute, for that very reason. Posted a preview of one on my FB page, and sold $100 of v carved name plaques yesterday.

racedirector Tue 19 May 2015 18:40

Oooo, do show us :) I just invested in some Amana Tools V groove insert bits they I am itching to try out. Not 'til Monday though.....

hennie Tue 19 May 2015 23:20

Shows you there is money in things we want to throw away.

Darren... Read through your thread. Great build and amazing thread. Really appreciate all the photos and documentation before and after. I'm planning a similar build. x = 62 y = 120. Do you think the shaking you mention early on after completing the build is because of the minimal lateral bracing in the x to accommodate material storage? What would you tweak about your frame design if you were to do it again? Any surprises by building the gantry extra wide? Appreciate it!

darren salyer Fri 17 July 2015 06:15

Thanks for the compliments.
I have an overabundance of bracing in the X direction. I'll assume you mean the Y.
This machine has a ton of mass. the legs and all the structure under the beams are 3/16" wall. Feeling the machine shake is different than having something show up in a cut. It cuts rock solid with no perceptible flex.
My only change would be to use thinner wall gantry beams, with a bolt strip inside, to reduce the weight of the gantry. I don't believe that would decrease cut quality, and may allow a small speed increase.
Temper that with the fact that I believe 120IPM is the limit of my cutters, (mostly 1/4" and 1/8") and router HP. On the rare occasion I use a 1/2" bit, I use 150-165 IPM speeds, which the machine handles with ease, with no lost steps.
Good luck with your build.

You need to make the jump to a spindle someday Darren. I have been waiting for that report. :D

domino11 Fri 17 July 2015 09:55

And a laser Darren!

Tom Ayres Sun 19 July 2015 06:16

Me! Me! I want a laser too!

darren salyer Sun 19 July 2015 18:48

Lol. How about we take up a collection for #101s member requested upgrades?

pblackburn Sun 19 July 2015 20:17

I am up for that

darren salyer Mon 20 July 2015 08:34

Was it this forum where someone posted a link to a DIY diode laser made into a bracket that mounted to the router housing?
Of course, I found it intriguing, and now I can't find it back...

servant74 Mon 20 July 2015 08:53

A little CNC machine to laser burn. Ripe to take the laser and power supply to hack for mounting on the MM!

darren salyer Mon 20 July 2015 08:59

I'll look into that one Jack.
Heres the one I was thinking of.

I remember seeing that one some time ago.

Just never found a laser similar to what he used.

Just found it: http://stores.ebay.com/KALE-CNC?_trksid=p4340.l2563

darren salyer Mon 20 July 2015 10:36

Me too, came here to post link...
I'm thinking I may need to order one up...that small entry level machine I started with would be ideal for this....

servant74 Mon 20 July 2015 10:40

Laser only machines can be much lighter because they have almost no mass required in the heads. Some just carry mirrors but from what I read they can be pretty hard to align. So for me, mounting a LED laser directly on the head is worth the little extra heft required.

darren salyer Mon 20 July 2015 10:41

A few posts back, I mentioned cutting plaques for a guy with a plasma, of course, he sent me a pic of his most recent cutout, and I had to have one for the shop wall, in 14g. steel. 48" wide... I think its cool.

darren salyer Mon 20 July 2015 10:53

Jack, that seller has a slightly more powerful Infrared Laser for the same price...Know anything about the difference between that and the one he used?

domino11 Mon 20 July 2015 10:53

This was the one I was thinking of, it was on a facebook group you are in Darren,
