Hello, I've followed the tutorial here to generate my drill file http://referencedesigner.com/tutorials/allegro/allegro_page_9.php and I have even viewed the drill file on an online gerber viewer and I can see the holes, however, my manufacturer (ALLPCB) says the drill file is empty. I have attached my drill file to this link https://ufile.io/r9pb4, can anyone spot anything wrong with it? Many thanks.
Hi James, I can confirm your drill file is not empty but what's going on is more than likely their tools are choking on what Allegro is putting out.
NC Parameters:Enhanced Excellon Checked "Believe you have this checked"Trailing zero suppression checked.Coordinates = AbsoluteOutput Units = EnglishFormat = 4 4 "Your format may be different"Offset x, y = 0
NC Drill Auto Tool Select Checked "Your file looks like it has not got this enabled"Repeat codes CheckedOptimize drill head travel.After you generate the NC file, check the log. (View Log Button)I did some tests with a high-end, industry standard gerber editor that is capable of pulling in NC drill files. When using Enhanced Excellon format and if "Auto tool Select" is not enabled The gerber editor will not import the allegro NC file. "Probably an Allegro Bug"
Give the above a try and see if all is working.Paul.
Hi Paul, I followed your steps and the PCB manufacturer has now approved the PCB for fabrication, thank you for your help!
Sounds good James.
Glad that worked out
