Changes noticed in 1.171

[Digitalwoodshop]

I upgraded to 1.171 the other day and today I cut 3 signs and was in for a rude supprise...

When doing a Bit Change the Cut Motor now spins up L O N G E R... And as a result is still coasting to a stop when it does it's Bob down toward the Brass Roller.... The First time it did it with the V90 I was not really paying attention but the V90 made a BANG as it hit something down there... Same with the 1/16 Carving Bit....

The Next Sign was a 3/8 plunge bit and a V90.... The 3/8's was not very happy with the meeting of metal and plastic.....

This Third sign I am using a V90 and 1/16 inch carving Bit... I open the top cover after the Cut Motor spins up and let it STOP then close the lid and press Enter....

This is more work for me.... Un Fix it please. It was fine before in 1.153, my last version.

Thank You !!!!

This has been a Public Service Announcement from Pocono Digital Woodshop.

Another new thing....

Just went over and flipped the 2 sided sign and the first strange thing is when it went to measure the board width it started normally at the left side or brass roller side and progressed one inch stopped and came back and measured the brass roller edge..... Back and fourth quickly about 20 times.... Only 1 inch of travel.... It is times like this that I wish I had a Video Camera recording the machine.... I opened the cover and it stopped.... Closed the cover and pressed Enter and it did it again about 10 times...

I then opened the cover and rolled up the head and wiped the Board Detector Window. Cranked it back down and had the Continue or Abort menu.... (THANK YOU FOR THAT.... IT SAVES PROJECTS and TIME..) Hit enter and it continued on normally measuring the board...

Then the Second thing I noticed was the Spin Up time for the Front Side of the Sign was normal for the 1/16 inch carving bit but just went over and changed to the V90 bit and it was still spinning on the way down to the brass roller and I opened the cover.....

SO.... LHR.... You need to test the Cut Motor On Time for Bit Change WITH a HEAVY BIT to account for the mass of the bit....

My High Millage machine is getting close to Cut Motor Brush Change time so the brushes are not providing as much Resistance to the Cut Motor along with my well worn and lubricated Flex and Spring damper.

And we still have the Check Cut Motor on Startup for the first Carving bit or V60 or V90. First 2 projects no CCM.... Thouight it was fixed.. But the 3rd had it...

Interesting.....

Glad someone noticed and reported these things as I was about to upgrade. Sorry but I think I will wait as mine is running just fine with 1.164. Hope LHR can get these problems fixed before someone ruins their machine. Thanks Al

I think new FW will report a error if the table is not even now.. I gotten into the habit of loading the work off center so I can lift the wood to check table pressure.

I've been using 1.171 and haven't noticed any of the problems mentioned in this thread. Bits all spin up normally and haven't had any problems with board measurements except when carving foam. With foam I've had to place a small piece of poster board under the bit when it does the "finding surface" part. The foam is not dense enough to stop the bit otherwise.

Unless it is my imagination but the Cut Path Feed Rate is looks faster on 1.171

Doing a .4 cut path today and the sound was ugly.... TOO fast with a 1/8 inch cutting bit...... Late this afternoon I snapped another 1/8 cutting bit.... It snapped while making the second pass in some clear pine.

I checked the bit on a earlier bit change and it was sharp and clean..... It was just cutting too fast....

I could have selected a 1/4 inch bit but I am not sure how the tabs would work assigning a depth to the bit...

I looked at the Bit Selection in 1.171 and it is still 1/8 and 1/16....


I will toss this out.... LHR? Why don't we have a 1/4 inch Cut Path selection?

A FEED RATE Slider would be good too....

I am looking at buying all the 1/8 inch cutting bits from Ask Bud..... I am getting low....

Thinking out LOUD......

Has anyone else been getting fatal error 3 with update 1.171 i had not got that in the pass but since upgrade i do. As al has said in some pass coments it could have some thing to do with the way the computer stores the data when you pause or stop a long carve (he put it much better than that). So on long carves i have just let it run and have had no probleme but as soon as i pause it or open lid i do.

When I did the August P.O.M. and was working on the photo holders, on the very first one my 1/8 cutting broke. Only had maybe 1 hour usage on this bit. When I used a new bit, oh the sound it was making while going through Walnut. Now the program was set to cut completely through 1/2" material instead of 2 passes. My wife was up stairs and she came running down because of the noise. I went ahead and made a timplate and will cut them out myself next time instead of the CW doing it.

This does not help but I set my max depth to .32" anything more tends to be risky.

[Digitalwoodshop]

I hate to say it.... But feet dragging in fixing the feed rate does cost us $40.00 a pop..... Yes, the work around is setting the depth to .32 and 3 passes..... I snapped the last bit with a .4 second pass....

2 Passes and 50% chances of a X tracking error snapping the bit.... 3 Passes.... Well.... In the Casino's... The House Wins..... I bet sales of 1/8 inch cutting bits is UP.....

It's time to add a Feed Rate Selection to Designer and a 1/4 inch bit for cut path ...

I am tempted to go back to a older version of Designer where a .4 depth looked slower...

Disappointed in the Pocono's...

I'm afraid I haven't changed the 8th inch cut feed rate since 1.152.

I've tried cutting with a 1/4" bit - the machine didn't like it very much.

[unitedcases]

I myself steer away from many projects just for the sheer fact that there is a cutout and I dont feel that I can do it as well as the machine can. And if you set your passes light then it takes forever to cut anything. 60 minutes on the machine or 5 minutes with a jigsaw. The cut rate should definitely be a option.

Metallus, was your test done with a CarveTight spindle? maybe problem was caused by torsional resonance in flex cable, spindle/chuck assembly & better balance with CT could be a better match of components. Thinking out loud, maybe too loud?

Metallus,
I think what Al is saying, is that we need a slower "feed" speed option on the Cut-out selection.
His other "make-shift" solution would be assigning a 1/4" bit in the Cut-out selection and then he could substitute his 1/8" bit and avoid the possible breakage factor.
Quote: "It's time to add a Feed Rate Selection to Designer and a 1/4 inch bit for cut path ..."

The problem lies in the fact that the "feed" rate need to be able to be changed to compensate for the various wood hardness situations.
A Tool maker would adjust the Feed Speed on each type of metal as required, and we need the same abilities.

Amen Brother!
Pine vs Walnut same feed rate. Are the results the same cutting .5 depth? Sometimes a broken $40 bit. That ain't fun :(

Is there a limit to how slow you can make the feed rate due to the servo increments of resolution? As seen if we try to cut very very small centerline text... Resolution?

Yes, a Feed Rate Selection would be good. Correct me if I am wrong, but does the Cut Path use 2 feed rates now, 1 slow for turns and corners and a faster rate for long areas.... It was more easily seen when I cut out a sheet of tags using vector lines and assigning the depth of cut using a 1/16 inch end mill bit. The corners were cut slow and the long lines were cut faster. No tabs, I use double stick tape on a carrier board.

If your snapping 1/8" bits it time to except the fact that .50" deep is not a good idea, and reduce your patterns to .32" deep for the max pass.

I also use the 1/16" carving bit to cut thin wood .21" max and had good results, except now i get the silly "cut motor error" when the bit hits the top of the wood before cutting for some reason.
