Re: chassis dimensions for 3d print

Not experienced with combat bots, but I do run a 3D printing company :D (DLP FDM SLA DOD SLS methods) so i can advise on that. Go with 100% infill :) For a thin 1/2mm wall, you will not use many more pence of material, but will be much stronger. Also increase your feed rate slightly so it overextrud...

Re: chassis dimensions for 3d print

What material will you use?

For example, PLA or Polycarbonate is going to make a big difference to strength and thus the thickness you will want to use.

Re: DisinfectANT - Antweight First Build Log

Silicone wheels. Not bad at 1.1g each. The hubs are cast in polyurethane, cheap and very light with excellent impact resistance like a thermoplastic. https://preview.ibb.co/eTKZkf/IMG-20181015-103836.jpg Silicone went for 25 shore hardness as i wanted it soft and grippy. Time to build the main chass...

Re: Team Antiquarian build diary

Looking great! Im envious of your speedy progress :D Wish my projects moved this hastily forward
I always love the look of see through bots like this. Definitely agree you can lower the wedge angle. Good luck with the next steps!

Re: DisinfectANT - Antweight First Build Log

Slow progress! Went on holiday for a few weeks, working like mad on regualr job to catch up. But managed to start test 3D printing some parts to test the fit. Seems no tolerance is needed to fit the wheels on the motors snugly after all. https://image.ibb.co/bzH95p/Dk_Op_Wb_FXg_AIt_C6p_jpg_large.jpg

Re: DisinfectANT - Antweight First Build Log

At last some free time to start cutting bits. The table saw is actually much more accurate than i thought for cutting small chunks (considering the size of the blade!) Inside 1mm will be fine as the stock is machined in the mill to be accurate :) https://image.ibb.co/cjUWzo/IMG_20180606_184538.jpg S...

Re: What is it with Americans and imperial units?

100% :lol: Was looking for end mills yesterday and kept finding things like 6.35mm diameter ... oh quarter of an inch well that's useless to me :-? Just remember an inch is split into 16ths, 12 inches to the foot, 3 feet to the yard, 220 yards to the furlong, 8 furlongs to the mile and 3 miles make ...

Re: Disinfect-ant - Antweight First Build Log

There hasn't been an ant called Disinfect-ant in the many years I've been around, though there was one called deoderAnt, which would've made for an interesting sounding battle... Awesome :D Thanks for the info on name. Maybe I can keep up a theme of household product ant puns :P Wow I'm loving this...

Re: Antweight First Build - EddieJ

All the new toys are here now :D nice to be using something which isnt a 3D printer for a change! https://snag.gy/edARHW.jpg I did a load of research on suitable mills for producing small accurate parts in lots of materials - the only sub 5k mills which would cut it (heh pun) were the Sieg K1 or the...

Re: Antweight First Build - EddieJ

Hi Mark, Yea that's it. 2x 1S batteries in series to make a 2S. Apologies about my scribbles, i dont have photoshop on my home PC, paint is ... less than ideal! :lol: I think from what you are saying I am on the right track. The orange lines are just me showing the point where I'd need to put in a P...

Re: Just getting started..

Hi Pudsey, I'm pretty new here also, but i think i can answer one of your questions, from what I have been told recently :D 180mah 2S will be fine for the battery. If you want to 3D print a chassis, send me the CAD file (STL or OBJ) all set up and i will print it free for you on the Ultimaker :) Are...

Re: Antweight First Build - EddieJ

More CAD and starting to put things together. :D Hopefully one more week and there may be something that resembles a robot on my desk! :lol: Lathe works well for nylon. A little grow at the end of this test piece, i should have locked the part in with both sides of the spindle. Then will be fine. ht...

Re: Antweight First Build - EddieJ

New toys and components arriving now :D Some bits needed lathing from nylon, so picked up a mega cheap 12v micro mill. It's manual and not CNC, but for the simple connecting rods which i need, it will be fine. Even if the accuracy is going to be something like 0.2mm, judging from the loose axis.. ht...
