Tool offsets

October 27, 2017, 4:48 am

In all the instruction from Tormach, or what I see on youtube, setting tool offsets use a similar technique: first you set reference point in each axis, using either the tool holder itself or a reference tool to set the master reference point. From here, you set each tool by touching that tool off to the work using a piece of paper, or feeler gauge or similar to determine when you are touching the work. In both the X and Z axis.

But, it seems to me that for the X position, it would be far more accurate to take a cut with every tool, measure work diameter and use that as the touch off value. X is absolute - it is not dependent on anything. The Z is not absolute - so it needs to be referenced against your master position and the paper or similar technique is the only way to go.

Anyone do it this way?

Hey you all,
I am planning to use an SBR25 round rails in my new build. I am not able to find any aluminum extrusion type that has a 35mm distance between two T slots.
SBR20 and SBR30 has a distance of 30mm,40mm, receptively and can go nicely with 6060 and 8080 type. Any suggestions would be appreciated.

Newbie Ready to pull the trigger on a CNC router

October 27, 2017, 5:41 am

I am an engineer and a woodworker, spending some of my work days in AutoCAD and Fusion360 already, it seems like the next logical step to bring a CNC router into my home shop.

I am having a hard time narrowing down a direction to go and a budget that I should be searching for. The hobby shops have the $5-6k options pre-built and ready to go, but I feel like that must not be the best "bang for your buck"

I have been looking at CNCrouterparts.com options and am having a hard time figuring out which direction to go. If I went with one from CNCrouterparts, I would probably go with a 4x4 table, but the price range from their standard to a fully loaded pro system can range from ~$4k to build it your self and do the wiring of the panel myself, to ~10k for a fully loaded NEMA 34 pro system.

I hesitate to go lower end, other than the fact that I am very new to this, I work with a $1M 2 station 5 axis CNC at work so I feel like the interest is there...

Anyone have any experience with being in this stage and any advice based on the direction they went?

am I better off spending $3-4k on something like a shark or axiom machine and have something up and running out of the box to start?

THANKS!!!

Dan

It starts and then it errors out with a E458 Soft Limits reached in positive direction. How to I view and edit my soft limits? Thanks in Advance!

Just In CNC machines for sheet metal processing in India

Hi everyone!!!

I plan to establish a metal processing unit in India to produce metal panels. At this starting point I need one turret punch press like Amada's AE 2510NT or Trumf's TruPunch 1000 and one bending press like Amada's HFE M2 1003 or Trumf's TruBend 3100.

Tryed to find quality machines made in India, but unfortunately I could not. Then I wrote to Amada and Trumf, which are present there, but still got no answer. They just ignore my mails.

There are two questions I would like to ask all and would really appreciate if anybody helps me here:
1. Are there any adequate CNC machine producers in India that you can suggest?
2. How do I approach big names in India to get feedback?

Additionally I would love to hear any suggestions concerning doing business in India.

Looking forward to your valuable answers and comments.

Thank you in advance,
Grigor

Switching from old parallel box to new controller

I have an old 3 axis K2 stepper machine that uses a parallel port setup that I haven't actually used in years due to family stuff. That's all over with so now I can actually indulge in my hobbies again!

The XP box is really flakey and I'd really like to switch up to newer hardware which means windows 10. I have a USB to Parallel adapter (used for programming atmel chips which I don't do any more) but from what I hear windows 10 just won't do the bit banging the way XP used. I'm also interested in adding a 4th axis so that pretty much dictates a new control setup anyway.

What kind of options do I have to upgrade the control system?

P.S. It'll be run from Mach3.

Is there an axis in-position window setting?

One of our guys is finishing up a project with a Mach3. He cannot find where to set what I am used to calling "IN POSITION WINDOW." That tells the mach3 when to go onto the next move command. Right now it must be set to 0 as it takes 3-4 seconds while we watch the following error reduce down to 0 before the next move happens. We want to set that to say 30 counts so it is responsive.

Can anyone tell me where that setting is?

Thanks.

Hi There,

I've been following this forum since a couple of years, now I need som help to solve an issue I have when milling round parts.

As you can see at the following pictures I'm having some issues with the finishing pass. The bottom is suposed to be round but at the finishing pass an almost flat area appear (not totally flat, but with a much higher radious than it should)

I use Rhino for CAM and Rhinocam as CAM. Milling machine is a Syil x4 speedmaster and I'm using Mach3,

Any clue about whats going on?

Thanks!!

So I am looking to get into the CNC business with a friend of mine. I am all about computers, Cad designs and custom wood working. I have been restoring and building custom 80's arcades by hand and I am looking to get a solution that will cut most of my time down.

I have been talking to Laguna, and they basically offered me a Smart Shop 2 4x8 system for about $43,900, but before I go blowing out the cost of a new SUV I want to make sure I am getting a Cadillac vs a Kia. who are some other manufacturers to compare with?

Any help out there?

WTH Is Wrong With The 'Zone?

The 'Zone has been pretty well hosed for the last 24 hours. It started 3-4 days ago, when one forum, Novakon, started getting incredibly slow. ONLY that one forum. Then, last night, they ALL started acting the same. Now, NONE of them display correctly - kinda like old text-based web pages, and they take 30-60 seconds to load, with virtually NO graphical elements displayed. This is with Chrome, IE, and Edge. Mobile site seems ok. But, all day it's been completely unusable...

Regards,
Ray L.
