[Emc-users] PII machine

2007-08-06 Thread aaron Moore
Hi list Am planning a 1.5m x 1.5m gantry style woodwork router. I have an old PII computer running at 222 hz. I have loaded ubuntu + emc, but can you tell me if I will be able to use it n a fairly basic router set up. Thanks for your recent answers Aaron -- Powered by Outblaze

Hello, Pete brings up an interesting point. Is it allowed to issue some MDI commands while in e-stop reset or even e-stop mode? AXIS (the GUI) simply disables MDI while machine is not switched on. TkEMC relies on task to do the right thing, and enables MDI and allows users to send MDI commands,

Hi there, Would my EMC2 system work with USB wireless networking? I'm thinking of this because I could connect the USB wireless adapter to a USB extension and position it for better reception. I'm just not sure if it would work on my Ubuntu Linux EMC2 system. Another option would be a PCI

Hi Aaron like in the Wiki described, about 500 MHz are O.K. my experiment with slow computers are: 450 Mhz PIII with 512 MB RAM: Installation works (256 MB RAM failed to install), takes time, Simulation O.K., but Halmeter and other diagnostics painful slow. 1.1 GHz AMD, 512 MB RAM works

While I can't comment on the wireless network other than it should work. I do have some comments on steppers and encoders. Unless you have some real high rent stepper drives capable of running your steppers at rediculess micro step counts encoder feedback is poimtless. First thing a proper

My opinion. Possibly in e-stop reset, but NOT in e-stop itself. This is a safety thing, if e-stop is generated by hardware NO further operation should be possible until the operator acknowledges the e-stop. Steve Stallings -Original Message- From: [EMAIL PROTECTED]
