View Full Version : Another Router Project pminmo 12-04-2003, 07:01 PM I'm really just getting started, but thought I would share some pictures of my router project: http://webpages.charter.net/pminmo/mycncpage.htm I've been working on it slowly over the past couple of month's. balsaman 12-04-2003, 08:22 PM Looks good. keep it up. Eric DDM 12-04-2003, 09:48 PM hey, just wondering where you got your driver boards and breakout board? other than that it looks great, keep us all posted pminmo 12-04-2003, 09:56 PM I did the design of both. I'm also doing a chopper board based on the 3977, but probably won't finish it till after the machine is done. The 5804 board I did to get a stepper running. Figured it would be much simpler in case of problems. And the steppers I have are 7.6V 1A steppers. Phil DaSigntist 12-04-2003, 10:47 PM Awesome, Allways fun to see the start to finish pictures! ezland00 12-05-2003, 07:42 AM Very nice job, Can't wait to see more. High Seas 12-05-2003, 08:37 AM Cool - love the price of the gear too - you might be at the low-end of expenses too! A good data point fot the ultimate resource challenge - use mail order bits and pieces! (How was Enco to deal with?) :cheers: Jim pminmo 12-05-2003, 06:12 PM My dealings with Enco have been great. My last order the shipping and handling was around $4 for $25 worth of stuff. Seems like everybody is $6 or more these days. Received two emails, one confirming the order, one the next day confirming shipping with a UPS tracking number. ezland00 12-15-2003, 08:37 PM Where did you brought those alum. rectangle tubing from? pminmo 12-15-2003, 09:13 PM Shapiro Supply http://www.shapirosupply.com/ I live in the same metro area and picked it up there. ezland00 12-22-2003, 02:28 AM how will does those Bronze bearing slide? pminmo 12-24-2003, 05:26 PM Not sure the bronze bearings are going to work. The bearings by themselves on the shaft move fine. My plan was to build a "pillow block" pair out of mdf and mount on one side and use roller blade bearings on the other. My thinking was I outght to be able to hold one side true, but any skewing would cause binding, thus the roller bearings on the other side. Well I'm having problems with skewing just on one side. I'm about ready to punt on the bronze bearings. limbo 12-25-2003, 06:26 AM pminmo, Great looking machine. Have you considered using two leadscrews? That would solve the binding and yawing. On a 24" wide machine you need real stiff bearings with considerable preload to get acceptable yaw, otherwise you would have to make the gantry more "square". In my machine theres still some 0.5mm yaw left when I push it hard. greetings, John |
