Re: CNC Machined 3-point Steady - #LATHES #CNC #CSS #DRO #RELS

 

<You can read a 100 different for and against bearings on steady rest.>

Hi, Ralph,

Having used it without bearings numerous times, I can't think of a disadvantage of adding bearings. At any rate, I am making new "fingers" for the bearings, so I can always change back if it actually becomes an issue.

Re: CNC Router Pendant Controller - I want to micro step to start at 0,0,0, #WOOD

 

Gentlemen, you are far more advance then I am.? This give me an ice cream headache, and I haven't ate any ice cream.
Thank you though for entertaining my novice, pretend hobbiest questions.

I make things for me related to my hobbies, I don't sell anything.? I've got a long list of stuff to make me.? Like...I want make myself a very cool box of drawers to hold my collection of silk sewing threads... drawers with glass fronts so you can see all the beautiful colors....? My dear husband is pretty smart, instead of me giving him a list of stuff I want, he gives me a CNC router to figure out how to make it myself... the Guys a genius right?? And as of now, I have all fingers intact and have never injured myself.? Another cool cabinet for my unimat lathe... she is a beautiful little lathe... for decade + when I can think about retiring, if I am blessed with good health.

From:? Jim.Klessig@...
It sounds to me like you have more than 1 issue. One is getting your pendant working,?and the second (from what you originally said),?it sounds to me like you are ending up with missing steps which I think is a bigger issue.?That could have a number of possible causes, some of which could be mechanical, some could be electrical, others could be software.

Yes, you are correct, the "homing" back to 0,0,0, was fixed when we removed the parallel port connections and went to USB.? The need to be ultra precise, this is my own issue...it is probably no big deal in the rest of the world.? But how much runout is acceptable if you are turning a piece of metal in a lathe.? +/- tolerance.

The migration to Planet CNC TNG fixed it to the tolerance of the steppers.??

From John Dammeyer:? "The learning curve for installing?LinuxCNC?and getting it working is steep."
Yep, this is reason enough for me not to try this.


This is my email, any suggestions?? <lol>?

Hi, I have Planet CNC / TNG that I purchased from Digital Wood Carver for my? CNC Router.? The system runs a gecko540 and is connected to a laptop with USB.? Does the software, Planet CNC/TNG allow me to add a pendant controller?? If Yes, please advise if you have instructions for me to add the pendant controller.? I do not like using my laptop keys to move the router to a specific point that I want to start carving from and when I tell the router to return to 0,0,0, it could be off 1/16" of an inch and then I have no confidence in running a two sided job.? It takes me approximately 6 minutes to get the router back to a marked with pencil start of 0,0,0 to run a 3 minute job for a 2 sided picture frame.

Realistically on this oval frame that I'm trying to make for a mirror, would be so much easier with a pin router.??

Thanks,

Tamra

Re: CNC Router Pendant Controller - I want to micro step to start at 0,0,0, #WOOD

 

¿ªÔÆÌåÓý

I have a JGRO CNC Router.? Here's a web site where someone described their build process.

Mine is a modified version of that which it seems most people do at some point.

I used a PMDX-125 Break out Board for it and MACH3 along with a Shuttle Express pendant all running on WIN-XP.? It's now like my table saw.? If I need wood routing I switch it on, insert the USB stick with the G-Code and carve something.? At one point many years ago I even mounted a nozzle and tried 3D printing with it but the machine is too massive for the fast motion required by 3D printing.? At the moment it has ball screws on X and Y.

?

Anyway, from there I went to adding CNC to my mill.? I built up a dual boot PC with MACH3 and LinuxCNC and the major requirement was that it had to run with parallel ports so I bought the newer PMDX-126 break out board.? Although it worked well enough I found that with the bigger DC Servos it really wasn't fast enough for pure parallel port operation so I tried both the USB based Smooth Stepper I borrowed from the JGRO CNC router which worked well.

?

Then I bought a MESA 7i92H which uses Ethernet and creates two parallel ports. ?I now rarely boot that PC into WIN-XP and MACH3.? So it seems I've made the conversion into LinuxCNC.? Although if for some reason I really had to use Windows upgrading the PC to the latest OS, MACH4 and Ethernet Smooth Stepper would work.? But why would I pay over $500 to get the same thing for free except the $89 MESA board?

?

For the mill I use the "HB04 USB Pendant".? Search Aliexpress for what it looks like.? Mine is a slightly older version but there is support for it with LinuxCNC.

?

The learning curve for installing LinuxCNC and getting it working is steep.? It may be easier to rewire the machine to use one of the more extensive Ethernet based BoB controllers from MESA.? Best ask on the

Re: CNC Router Pendant Controller - I want to micro step to start at 0,0,0, #WOOD

 

I'm using Mach4 Hobby on a LMS3990 converted to CNC. I purchased the ShuttlePro v2 for a pendant and it all works fine together. My electronics are PMDX-411 and 340. I've never used the Path option in FreeCAD, but Mill Wizard has done everything I wanted, so far. I believe the smaller ShuttleExpress would work as well, but you'd have to ask the guys at Mach4. I only use the X, Y, Z buttons even thought there are many more assignable buttons on the ShuttlePro.

Are my questions reasonable?? Am I asking the question with the right words?

I'm going to contact Planet CNC TNG and ask if I can use their software and can add the pendant controller.

If I am unable to add a pendant controller to the Planet CNC TNG then I have to migrate to a different router controller (Mach 3, linux, etc) or upgrade to their other option.

Is my logic (related to my digital problem flawed)?? I admit my logic was flawed when I thought it would be fun to learn how to use a CNC router.

Hi, Barry,

I agree 100% re John's Steady!

My Real Bull also came with Steady and Traveling Rests, but my 3-point Steady Rest is not split, I.E., it will not open like John's. He has suggested that I modify it, which should be a simple little project.

It was great Skyping with you the other evening! (Well, morning for you Down Under!) Have a good time in the shop today!!!

Hi, Tamra,

I have a friend who built his own CNC router. If you still have not resolved your issue, I can ask him if he minds contacting you, either here or elsewhere, and sharing how he handled the electronics and software. Please LMK if that would be helpful. I do not know what hardware, software or OS he is running.
