FAQs / Re: Whats is most actuate set up for limit switches
« on: June 29, 2015, 11:49:45 AM »
thank you for you feedback ... I have not used an encoder before.  Are they attached to back side of the steeper or to the shaft in some type of manner.  Are there any preferred suppliers or websites I can educate my self on there use.

FAQs / Whats is most actuate set up for limit switches
« on: June 26, 2015, 10:48:06 AM »
I am using MACH4 with a ESS controller I would like to very accurately home each time my machine starts up.  I need to be able duplicate my home position every time so i can place parts in a automation project i am building.  Is there any one on the form with some experience how to best approach this type of thing.

I am guessing an optical limit would be best ... any feedback would be appreciated.

SmoothStepper USB / Connecting ESS to MX4600 Driver
« on: June 22, 2015, 05:27:16 PM »
Has anyone configured an ESS to a Leadshine MX4600 driver/BOB?  I am not seeing to get the two talking as of yet through MACH4.

SmoothStepper USB / ESS Mounting Case
« on: June 12, 2015, 01:08:27 PM »
I had no way of mounting my ESS board effectively and both connect from my PC and interface to the ports so I designed a case for it and printed it on my BOT. Worked out nice protects everything and I can get to all the connections.  It can be mounted on 3 sides.  I used the face in my application so I could interface to it directly from my PC.  Attached is 3D PDF so it can be seen in detail.

Steve ...   I am finding it seems one needs to educate them selves thoroughly before buying this CNC gear.  Oh well at lest i am learning while wasting a several dollars!  FYI i look forward to seeing your new pulsed/MACH4/Ethernet based board in the coming months ... i will be one of your first customers!  Comment about your design ... with the MX-4660 4 axis (expandable to 6 axis) driver system it comes with a breakout board built into it ... is there any though to making a version of your new controller with just the port outputs so i can connect directly to the Leadshine board via a ribbon cable (sorry being a bit selfish)? Anyway I am pretty good at LED power supply's but I am a stepper drive idiot so take my suggestion with my knowledge base into consideration.

Anyway back to my system

I will be using 4 Chinese ACT-Motor 23HS2430B to run this machine, they are 425 oz 3A 112mm ... FYI i will be gluing, testing and putting lens on lights, we do 20,000 unit builds at a time so i need speed!  I need speed in X,Y,A and both speed and as much power as possible in my Z axis to snap a polycarbonate lens to a heat sink.  Again not knowing the proper application for selecting motors these are what i purchased to date.

My plan is to use MACH4 and to customize it with some basic scripting to flip and read some inputs and outputs to run a few air actuated devises and a vacuum pump.  I for one have never heard of Lua, but from what i read this language it the cats in the gaming world and for scripting.  I hope at my age this old dog can learn it. I sure hope there is some individuals on this form who can give me some direction.

I have a few other questions which i would sure like some one with experience to educate me.

Q1. I notice the wires on these steppers are very small and the peak currents are fairly sized.  Should I keep the wire from the stepper very short and connect to it using shielded say 18 gauge 4 conductor wire to the drivers?

Q2 How much is does noise play havoc with these systems? Does one need to add some input capacitance on the output of the supplies?

Q3 Are there much issues with ground loops in these systems?

Q4 Are there any best practices for connecting the various power supplies grounds.


anyway hope i am not out of line for asking so many questions

Steve,

Thank you ... you being a manufacture of such devices I want to commend you on our comments ... as my grandmother would say "If you cant say anything nice don't say anything at all!  Thank you for the information you provided it was very good of you and shows the ethics of you and your company.

My application is to build a automated machine to assist in building lights we design and manufacture so speed and decent accuracy are important to me.  Question ... does the smooth stepper type controller provide the best option for speed and torque on a steeper motor?  I have watch a few videos on YouTube and seen presented differences.  Is Warp 9 the only company who offers this type of controller currently or are there other manufactures?

Currently I am trending toward a Warp9 Ethernet Smooth Stepper with a Leadshine MX4660 4 axis DSP digital stepper drives ... Your comments to this type of approach would be appreciated.

I am looking for a  controller that i can get good support on ... at least someone I can call on land line for sure!
1. Can anyone tell me whats the deal with what are referred to as smooth stepper controllers like Warp9 or TinyG ... is there any benefit to these types of controllers?
2. Can a Tiny G controller work with Mach3, Mach4?
2. Is there much difference between Warp9 ... PMDX and Vital Systems controllers.

FYI i tried buying a Chinese made XHC 6 axis controller but i can not get any support with my drive issues.

Thanks  Scott

I am new to g-code mode commands but i believe G64 is listed on top of screen in Mach3.  I used the wizard to create the code to simulate cutting a 100mm radius circle for my test.  Is there something else I am missing?

Thank you for you help!

I am creating a automated machine to help in the production of some lights we manufacture.  I am using Mach 3 to control a 3 axis table but i am having trouble getting the axis to run smoothly when i run actual g-code.  I have tuned the motors using the suggest motor tuning in Mach 3 and they work perfectly when i just manually move the all axis's.  Has any one ever seen this issue before.  I must admit i am not the most experienced at this stuff!

My machine hardware
Drivers: DM524 on all axis
Controller: USB XHC 6 axis made by cdhctech.com
Steppers: 23HS2430B 1.8 Deg 3 Amp
I have Steps per at 80, velocity at 2500 and Acc. at 750

Thanks

I will do that this morning first thing  ... FYI I want to thank you for being so helpful and patience!
