As probably the only dedicated Cannon Artisan on the server I can tell you it is possible to have fun with them. However....
Should you Craft with a Cannon build?
No, not really. You can get away with simple crafting like lvl 0-10 items for max stats + Alchemy. Maybe Gem crafting and PAT but it seems you're not interested in that.
Essentially, anything that majority rely's on CON and sub-stats aren't what you're after.
Can you use a Cannon?
Absolutely. In fact, Cannon Artisan deal out a lot more Damage, Farm Better, Have a better list of utility AND can tank a little bit more than a Gun.
Can you learn all crafting Skills?
Yes, you can, but you will never use that Artisan for combat until you reset it again. Hence, if you want ALL crafting skills, you should not use the cannon build as it's not a combat skill set, and the STR would be going to waste.
Some other things to take note of.
1: You will die. and you will die a lot.
You'll have absolutely zero defensive passives or buffs. Because of this, you need to focus 100% on offense. Kill before you die, or you'll lose period.
2: Use your explosives!
Cannons Passive Critical, Critical Damage, Skill Power, Pierce and Attack Power ALL stack into Grenade + Explosive damage.
They can be used while under the effects of Mute, because they're an item, not a Skill.
They can be cast in quick succession for a short but efficient burst damage.
3: PvP Items:
Luminous. You have no other choice.
Epic Cannon or Luminous Cannon. You have NO other choice.
Luna Jewelry. 13% Crit, 13% MSpd, 13dex[useless] 24 Con. Can be sub-stat. Your BEST jewelry set.
Ferrel Back Shield. Your accuracy is terrible compared to a gun, but with proper gear and stats, it can be good enough.
Gold Patch. Pretty much your only choice.
4: PvM Set:
Epic Cannon. Only Choice.
210 2/4 Set [Skill Power pieces] 220 2/4 set [Skill Power glove + set]
Luna Set: Sub-stat for AP/Crit
Doctor Arms or Millenium: [probably both]
Gloopy or Gold Patch: personal preference.
Hope this helps you get started.
But just remember, you've been warned. Artisan are the easiest class to kill. So expect to die, a LOT.
[and in PvM / Dungeons expect to be pulling aggro off the tank until the Taunt update get's applied, cause you will. All the time. And you will die for it, unless the cleric is on their game]
