--- Quote from: John Stevenson on October 27, 2016, 06:09:19 PM ---I have recently took delivery of the latest version from Rattn Motor called the RMHV2.1 Looks the same as the 1.1 but different legend membrane on the front. If it helps I have uploaded the manual here. http://www.stevenson-engineers.co.uk/files/RMHV2.1%20PLC%20offline%20control%20user%20manual-1.pdf Here is where I got mine from. https://www.aliexpress.com/item/EU-Delivery-4-Axis-PLC-Controller-500KHz-off-line-operation-for-CNC-Router-Engraving-Milling-Machine/32664122826.html?spm=2114.13010608.0.0.V9yTdt Later on I'll boot it up and see what version the software is. This is a 4 axis one. I can also download the firmware is someone explains how to do it it words of 2 syllables and Github and Sourgeforce must not be any of them. --- End quote --- Hello! After studying the manual and having a good look, I can say it won't be neccessairy to dump the firmware which you can do by heading over to the file tab and going up a folder and copying the linuxrc file and all files from the /mnt/nand1-1 directory to the supplied USB disk and copying them to a PC. Files can be copied by hovering over them and pressing the FRO button. Then heading over to the USB disk mount and pressing 2nd to paste the file. But your CNC controller will certainly run the same firmware with just a different membrane overlay. If you could tell us the firmware version we could see if this is a newer version. 2016-06-10-80 NAND is currently the latest one we got and the version I am basing my improved firmware on. |

On a related topic - what is everybody using as their stepper driver units? I ask because I have been using a set of 3 M542 (I think) drivers with a home brew and somewhat dangerous 32V linear supply which works perfectly with the DDCSV1.1. However I decided to upgrade this at the same time as the controller and bought a 4 axis board using TB6600s allegedly capable of 45V input - but specified on the Toshiba data sheet as only 42V max. Plugged it in, adjusted each channel for current and it howls, whistles, hums and every other known sound - and the nice chunky heatsink on the back *will* need a fan or two to keep it from going into meltdown. Guess it will do for the moment or I will roll back to the older one - whichever happens, I am in the market for 4 driver units for NEMA 23, 3.5A 200step steppers other properties not to hand! What are the preferred units - and ideally nothing in the mega buck department please! Simon |

They should arrive tomorrow. https://www.amazon.de/SainSmart-Router-Stepper-Drivers-axiscontrol/dp/B00898T40W/ref=sr_1_1?ie=UTF8&qid=1477608546&sr=8-1 What is your opinion on them? I am sure they should be enough to drive my Nema 17 steppers. They are based on the Toshiba TB6600 stepper motor driver IC: http://www.mouser.com/ds/2/408/TB6600HG-483084.pdf I have two supplies to choose from: a 12V 10A supply or a 24V 5A supply (which is also used by the controller). Any thoughts? Which one should I use? |

Simon, I use these: https://www.cnc4you.co.uk/Microstepping-Driver/Stepper-Motor-Driver-4.5A,-50V-CNC-Microstepping-CW5045 The drives and my 3.5 N-m motors run nice and cool (and quiet). My motors are rated at 4.2A with windings in parallel but I don't run them that hard. Cheers. Phil. |

That was the stepper driver i bought that did not work, i have a cheapO version of it on the rotab at the moment ..i think it was about £13. Lyn. --- End quote --- |
