Re: [Emc-users] Power and data cables for CNC

Re: [Emc-users] Power and data cables for CNC
Rafael The wires you need will depend on what motors you are using, the arrangement of limit/home switches and if encoders are being used. Once you know these things you can choose the cable. For example I have built a machine of similar size to yours. It's driven by three 3.1Nm steppers with no encoders. The steppers each need four wires and are driven at 4.5A so I choose 24/0.2 wire to carry this. I have two limit and one home switch per axis so I need six signal wires per axis. I could have combined the 0V line, the I would only need four wires, but felt this would limit my options. I have used CAT5 cable for this, but now find that I may have to replace this with shielded cable.

I was hoping to get a simple answer based on real life experience, get this or that cable with x number of shielded and stranded or twisted wires ;-) That's why I mentioned size as that would give one an idea of motor sizes and other requirements. Is it better to have one cable with x number of wires to take care of all needs or a number of smaller cables (y) with x/y wires?

[Emc-users] Joystick Pendant
I've just 'wired' up a joystick to use as a pendant, based on the Simple Remote Pendant article on the Wiki. As I only have two analogue inputs X Y (the third is normally used for throttle and does not self centre so I did not fancy using that) I used the trigger button to select between X Y control or Z control. However I notice strange behaviour on start up. I tracked this down to the fact that input.0.btn-joystick and input.0.btn-joystick-not were both false until the trigger is pressed the first time. Is this normal? I guess I can overcome this by using a not component. I'm using axis and would like to connect one of the joystick buttons to the touch off button, but can't see this. Is this possible? Can I link to keyboard keys so something like net touch-off keyboard.end = input.0.btn-bottom4 Mike -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Emc-users] hal 'net' command puzzler
As a new user I've been following this thread with interest. My only questions are: 1. What is the scope of a signal name. Is it machine wide or limited to the Hal file it appears in. 2. If machine wide, are there existing signal names in existence that I have to avoid re-declaring? Mike On 5 May 2012, at 22:31, John Prentice j...@castlewd.freeserve.co.uk wrote: From: andy pugh bodge...@gmail.com Every net command is followed immediately by a signal name. That is, a name you have chosen yourself, to make sense to you (or to confuse yourself horribly in the future, if you so choose). You can uses the same signal name on as many net commands as you like. But being a signal name it needs to be the first term after the word net Every net command with the same signal name will pass the same value to every HAL pin listed in the command. And that value will be from the one, and only one, output pin that appears in one of the net commands. I use the mental model that the signal is a wire and the signalname defined after net is the heatshrink sleeve printed with its name. The wire loops its way round pins (i.e. terminals) but, as the order of writing does not matter, the HAL is essentially a schematic not a wiring diagram. Of course woebetide the person who wires the outputs of more than one totem pole gate (or push-pull amp) together. HAL gives you an error if you try it and this prompts you to include a selector, or tri-state bus arrangement on the drivers. As an aside, as many nets are best written on one line, inventing the signal name is tedious. It would suit me to allow a wildcard, * or whatever, as signalname and HAL would invent a unique internal name for its own purposes.

[Emc-users] Limit max jog rate
Hi I'm planning to wire my limit and estop switches to a relay that will cut power to the spindle, disable the stepper drivers and inform Linux CNC that an estop has occured. I want do this this as otherwise there may be no way to stop the machine if a software error occurs. This means I will need a limit override switch so I can jog back off the limit switch. If I feed an output from this switch back into the PC is it possible to limit the maximum jog rate while the button is held in, so I can't accidently jog at high speed in the wrong direction? I'm not looking for a full solution just confirmation that this is possible to do with HAL commands. If possible I will set myself the challenge of working out how.

[Emc-users] Fixed Dwell
Hi I'm nearing the end of building a DIY gantry router. The router I'm using has soft start, so takes several seconds to come up to speed. I realise I could add dwell commands to the G-Code, but is it possible to add a fixed dwell to Linux CNC after spindle start. From reading other posts I see that HAL has a spindle-at-speed input that is intended to be used with encoders, but could it be used with a timer?

I agree. What I see the big issue for solving this in trajectory planner or whatever _inside_ LinuxCNC is that I do not see, how to determine by some hard facts, what is the best way to determine the lookup amount. Certain number of lines or a certain travel distance? Ok, when the method is chosen, how to determine, what is the optimum value? That is why I am in favor of adding a separate filter, which would take the code and rephrase it to what is really in there - either arcs or splines/nurbs. In this case the file would be processed, when loaded (I have not really understood, when it would be processed in the first variant - also on loading or on the fly, when it is executed), so it definitely would not affect realtime performance, because the file would not be executed at that time. I think that waiting 10-20 seconds for the PC to recalculate the path and find, what curves would fit the existing profile, defined by tiny G1s.
