Turns out it's a combination issue of my new controller handling a higher max speed (but keeping the accel lower to avoid wobble in the gantry in sudden direction changes) and the result of a newer...
I'm having an issue where corners are being rounded when there is no compensation or curves set in the GCode file, in fact the file specifically contains a G40 and G49 at the beginning to cancel any...
For some reason my machine refuses to now get through POST with it's 2nd parallel port PCI card installed so I can no longer use the spindle at speed input on it (Card works fine in another machine...
I'm struggling to work out why my motors (On all Axis so it's not just a dodgy motor) have started stalling randomly.
When I first setup my CNC I ran all the EMC tests to determine max speed and...
Thanks and sorry if that was a really basic thing, I haven't been doing this for too long. So that I can identify it easier in the future, what's the easiest way to work out these issues? Is there...
I thought that may have been the case in the first place and I tried moving the segments around but got similar results which is why I thought maybe it had to do with the inside/outside angles or...
Hi Scorch,
First I just wanted to say thanks for the work on F-Engrave! Secondly, I'm hoping you'll be able to give me some assistance with why I can't get F-Engrave to do this drawing properly. ...
That does happen. When I estop all power is cut, the spindle stops, the steppers stop completely (No longer held in position). The problem is then when I shutdown the PC, every pin on the parallel...
Being only new to this I'm not 100% sure of a 'recommended' setup. The controller I have is only a basic parallel Chinese one (HY-TB4DV-M) for a desktop mill and the estop it has only relays that to...
I'm not sure if anyone else has this issue, but I have a Dell PC with built in parallel port for my CNC machine and when I shut it down it seems to be sending all pins high which makes the steppers...
After thinking about it on the drive home today I realise I should probably leave the controller set to 75% as the power supply showing only 700mA with the axis in motion is probably due to PWM...
So I tested my machine yesterday with the controller set to 100% current and the spindle off, despite the steppers being rated at 3.0A when I tested it with my 'lab' power supply it went from 300mA...
I guess you should never assume that what the Chinese put on their boards is accurate! Thanks for the info John, I'm thinking I'll run it at about 30V (RSP-500-27 adjusted up) as per the 'How I...
Unfortunately one of the issues of having purchased a 2nd hand machine that you haven't seen working and has been modified is not knowing why the modifications were done. At this point I'm trying to...
Thanks for that info :) I can't run 48V because the controller isn't rated to that, the controller is a chopper type (Toshiba TB6560AHQ) so I'll probably run at 36V.
You mentioned that a higher...
Yes it does tick all the boxes of the 23HS8430 (Current, step size, physical dimensions) and is a bipolar motor. There's no mention of voltage on the spec sheet, would it be safe to assume 36V is...
I have no idea what the nameplate voltage is for these steppers as it has nothing more written on it outside of the photo shown. The controller supports up to 36V. The water pump that came with the...
I had been planning to make a CNC for a while and the guy I work for decided to be nice and purchased a table top CNC from an online auction. The only problem is it had no control box (Which had the...
