Thank you both for taking the trouble to help me.
I have done some further searching and I am reasonably sure that the MOBO is an RDLC320 as none of the others that I can find are anything like...
Hi folks,
I bought my Chinese 50W(?) laser some years ago and must admit to not be being very impressed with the performance of the laser. I reckon that the quoted power, as so many others have...
Thank you for your reply Pete and I note what you say about taking the pulse and direction signals from the parallel port.
In my new build, I shall be incorporating a UC100 USB to parallel...
I am in the process of building an OSD for my home built CNC machine.
The circuit utilises CD40110BE up/down/counter/drivers directly driving dual 7 segment displays. The ICs have an up input and...
Shielding was recommended to me by the guy from which I have bought most of my equipment. He said it is essential to prevent RF interference to nearby equipment and that he installs it on all of his...
I would not dream of using flexible conduit in the circumstances that you suggest. I do use it to route cabling on non-moving parts but if they were required to flex often, would result in the...
I am thinking that what you advocate is functionally achieved by what I have written in reply to Mactech54 above. Am I correct?
The picture shows the connection end of my spindle with just 3 pins in the Aviation connector. The black metal cap, body of the spindle and the aviation connector body all have electrical continuity...
Hi folks,
I am finally getting around to installing my Yuhuan VFD to my chinese, 1.5kW, water cooled spindle.
I have watched numerable YouTube tutorials on the subject but still feel uneasy with...
First of all, I apologise if I have come to the wrong section in which to make this post.
I am working on my design for an automatic tool changer that requires the tool holder to be slowly...
Hello folks.
I intend to use a microcontroller to run an on screen digital positioning display (OSD) but need to know something of the nature of the pulses sent to the stepper driver and/or the...
Hello John-100,
First of all, sincere apologies for not answering sooner. The cause was illness and that the notification went to my spam folder.
I am somewhat confused at the circuit diagrams. ...
Yes, the machine has been modified and the white socket is a standard British, 13 amp, 3 pin socket (twin and ground). However, I would guess that socket has been added for external equipment to be...
Hi Folks
I am rebuilding my home built CNC machine and have now fitted a 1.5 kW spindle motor with a Huanyang Inverter.
My original BOB was a cheap chinese, 5 Axis version that came with a hand...
I don't know if you are aware of it Dude but the rating of a stepper motor (pounds/ft, KG/Metre) is an indication of the HOLDING torque, not the cutting torque and so, when you have power applied,...
Thank you John, Ger and CNCman. I much appreciate your very prompt replies. Of course, the listing did not mention that the motor required a VFD. I suppose I shall have to spend out for one though...
Hi Guys,
I have been rebuilding and rewiring my home built CNC machine and bought a Chinese, 1.5 kW, water cooled spindle. It looks very substantial and thought that it would do what I need it to...
Hello folks,
I have been a member of these fora for some 2years when I first became interested in CNC and thought it may give me insight into how to go about building a machine. I am involved in...
I do not know whether I am off the mark here but I have come across this difference in Asian built motor shafts. They nearly all use inches instead of metric for the US market. 6.3mm equates with...
