Hello every one, Is there an dxf file for G100 layout. I am making a pc board. needconnector pitch, distance of pins from some reference etc. and pinout. ...
I miss-read your request. Can you use an ACAD2000 format .dxf? If yes, I will upload a 3D .dxf of the G100. ACAD R12 .dxf will not properly open 3D drawings. ...
Hi Jonny, Been running into a few power surges and dips in my area, I've installed a few APC 700 UPS inline. Most modern power supplies (switching) should be ...
HI guys, thanks for all quotations,i obtained roughly $28,571 (over 3 years) to make the whole assembly plant for low cost CNC gantries and CMM equipment.(and...
I saw this metal rack and pinion which comes as a tape. What do you think of it for wood routers?(3mm tooltip,slow-medium feedrate,for wood carving of motifs) ...
Jeet, The plastic will be fine just for a demo. How much force does it require to push a router through wood? And use balsa wood, he just wants to see it move....
... $28K wouldn't go very far in the US, obviously things cost out differently in Mauritius. Congratulations! ... Unless you find something unusual, you might...
... Cool product, but I saw this "caution" on the page : "These metal flexible racks are not suitable for applications where positioning accuracy is required."...
... But, he needs to have the demo as close to production as possible. ... But, they usually are pretty big gears. ... But, to have decent life, the gears have...
actually,i just need to get the prototype working,then all kinds of ministries will start to put up the funding.Pretty much everyone needs Motion Control these...
To alleviate acceleration,i will program Matlab to make a toolpath before sending pulses.Normally i step directly from computed x/y data. By making a toolpath...
How much force do you need? Its simple math really. Lets say you need/want 20 pounds of force to move your gantry. 20x16 = 320 oz-in of force. Now lets take a...
I would seriously consider toothed belt drive. Modern toothed belts have very low elasticity so you can get surprisingly good positioning accuracy. Have a look...
ok...that calculation reaaly helps.thanks Mr roger and Mr Jon for your kind advice. The tape racks suck! they cost more than rigid racks. i found 12 inch rack...
Hi, I am converting my mill to a cnc, and before investing money and time in fitting precision ball screws I figured I d launch this thought: Would it be...
... Hi, from my experience, belt drives are ok for machines with no or almost no side forces like waterjet cutters or laser. If the machines are no bigger than...
I'm wondering, with the weight of the gantry, whether one could get by with just plain old wheels- he's talking about 1mm accuracy, which sounds to me like...
Bram: I have heard people mounting the encoder to the ballscrew shaft, wouldnt know if its possible with your machine. A local guy has done it on a Tormach...
I'm used to thinking about mills with screws not a gantry configuration so consider my comments the same as a blind man offering help in crossing the road :-)....
very good idea. I'm also thinking,what if i make two side clamps that squeeze the belt directly on the frame.It could become a very very very cheap and robust...
... We go through this every few months. The problem is, just by knowing the actual position, you have not eliminated the backlash. There is a region where...
... Why don't you use EMC? It already has all the code to limit acceleration to any arbitrary value you specify, using the lookahead to slow down early on...
... You need to keep the belt under tension, with some sort of spring arrangement at one end, or a spring-loaded pulley. W. M. Berg has a selection of...
... Well, this is for a router, not a metal milling machine. What tension did you put that belt under? You can apply amazing tension to the belts with...
most probably i will. i don't see myself managing to get a Matlab software and a gantry ready in 1 month. + shipping delay. yeah,definitely EMC it is....
