Modbus / Modbus Basics

« on: November 17, 2016, 05:43:09 PM »

Can someone tell me were i can read or learn about how to utilize Modbus via MACH4 to control a VFD.  I have looked at the treads and i do not see anything explaining the use and benefits.  I understand its a type of network protical but how is it directed via MACH4?   Is it even available in the current version of MACH4?

Thanks Scott

I will give it a shot never sent a file on the form ... here goes

Note: Bad file uses a radial cut option and good files uses offset option in MecSoft.

Thanks for the reply Rob ...  FYI my spindle is a 2.2kW unit sorry missed that detail.  Yes the 6040 table is very much does lack for rigidity, its really weak in the Z, ok X and Y also.  I have found if I keep my cut depths around .012" to .020" it does OK for the metal test fixtures I am making with it. They do take a while to cut but come out pretty good.   If cutting wood or plastic it does very well.  I even made a 6040 into a production gluing dispenser that works awesome.  You are right though I need a stiff CNC for cutting my metal parts.  I am working on one from scratch on the side.

Back To Missing Steps:

OK this is what I have found working with the router all day yesterday.  I found that depending on what type of G-code I run the the problem goes away.  For example I use Mecsoft Vismill to generate my G-Code and when I use there Horizontal Roughing Offset cutting option the machine works flawlessly.  Its when I run there Radial Roughing option the machine lose's steppers every time within a few seconds.

So I know know when the problem accrues but i don't know why!  I Know its not G-Code ... but where does the problem come from.  Is it Mach4, Motors, MX4660, Warp9 ESS Ctrl and or combination.

I hope someone else has come across this problem also!

I have a 6040 router that i built from a frame kit that has been running fine for over a year.  Now while trying to cut an aluminium heat sink, I am losing steps like crazy, In I be leave both the X and Y axis's.  I have checked both X and Y axis and they are not jammed or obstructed in any way.  All Steppers seem to be running fine I think.  Has anyone ever experienced this before, and if so where do i look for the culprit?

Thanks Scott


My System:
CNC Software: Mach4
Table: 6040 Router Frame Kit
Steppers: 3 - 23HS2430B 425 oz. @ 3 Amp
Drivers: Leadshine: MX4660
Controller: Warp 9 ESS Smooth Stepper
Power Supply: KL5620, 55V 20 Amp, with 5 Volt Aux Output
Spindle: 400Hz 24,000 RPM, 220 Volt (Powered by Step-Up Transformer 110V to 220V)
VFD: Sunfar E500 (Powered by Step-Up Transformer 110V to 220V)

Is there a way to load G54.1 P1-P120 locations automatically when G-Code is loaded?

Thanks Bob,

I will see what i can do to attach a sensor to my spindle.  Hopefully i can get to top of shaft in some way.

Mach4 General Discussion / How to show Spindle RPM in MACH4

« on: July 15, 2016, 02:31:39 PM »

I have a Sunfar (Simphoenix) E500 VFD driving a Air Cooled 24,000 RPM 220V 2.2kW spindle (Note: spindle is powered by 110-220 AC step up transformer ST-3000).  I am using Mach4 to control its speed using a MX4600 driver with a ESS controller.  I have MACH4 controlling the speed and direction properly.  My question is how do I get MACH to display the RPM on its DRO in MX4 screen set.  Do i need some sort of feed back system or is there another way?

Mach4 General Discussion / Re: Problem with Z-Axis Direction when Soft Limits Active

« on: July 09, 2016, 07:15:25 PM »

Need to correct my problem statement the z-axis only goes in up ward direction when soft-limits is active!
No matter if i push the plus or minus button it always goes positive or up ward.

Sorry just wanted to make sure i have this right.

Mach4 General Discussion / Problem with Z-Axis Reversal when Soft Limits Active

« on: July 09, 2016, 06:37:16 PM »

I am using Mach4 with ESS and a Leadshine MX4660 driver.  I have got xyz axis's set up with hall detectors and when I reference all or any individuale axis they home properly each time.  Yet when I activate the Soft Limits button the directions of X-axis and Y-axis work fine but the Z-axis reverses direction when I press a plus or minus jog button.  Can some one explained to me what I have done wrong to have the Z-axis reverse movement directions when the Soft Limit button is active.
